CSF 20-24 Chevrolet Silverado 2500/3500 6.6L Radiator

The CSF radiator features a 1-Row 31mm aluminum core that not only increases the fluid capacity of the radiator, but also improves the cores ability to dissipate heat. CSF went through several different prototypes using cores of varying thicknesses. The 31mm core was found to be the best balance of performance and fitment. This sizing allows for use of an OE style clutch pull fan or an aftermarket electric push fan. CSF's Exclusive B-Tube Technology increases the heat transfer by approximately 15% over regular oval welded tubes. With nearly double the number of cooling fins and tubes, the CSF Radiator will outperform the OEM unit by a significant margin. In addition, the super-efficient multi-louvered fins maximize airflow through the core for the best possible performance. The radiator mounts in the factory location and requires no modifications or cutting.This Part Fits: Year Make Model Submodel 1967-1971 BMW 1602 Base 1966-1976 BMW 2002 Base 1971-1974 BMW 2002 Cabriolet 1973-1974 BMW 2002 Turbo 1971-1974 BMW 2002tii Base

The Bronco and Ranger's cooling system is fine for some drivers, but those who are pushing the limits of these rigs will put a strain on the factory system. However, it's not just those with added power and hardcore off-roaders that can benefit from an upgraded cooling system. Many overlanders, campers, and more casual off-road goers add a lot of weight and drag to their rigs. Accessories like Roof mounted tents, campers, spare tires, fuel cans, and/or towing can put a lot of extra strain on both the engine and cooling system. An upgraded radiator can mean the difference between non-stop action, and having to give your engine a break to recover from overheating or heat soak.This Part Fits: Year Make Model Submodel 2021-2024 Ford Bronco Badlands 2021-2023 Ford Bronco Base 2021-2024 Ford Bronco Big Bend 2021-2024 Ford Bronco Black Diamond 2022-2024 Ford Bronco Everglades 2021 Ford Bronco First Edition 2023-2024 Ford Bronco Heritage Edition 2023-2024 Ford Bronco Heritage Limited Edition 2021-2024 Ford Bronco Outer Banks 2021-2024 Ford Bronco Wildtrak 2024 Ford Ranger Lariat 2024 Ford Ranger Raptor 2024 Ford Ranger XL 2024 Ford Ranger XLT

The original OE radiator from Porsche is a plastic tank radiator with a single row aluminum core design. While this is generally accepted as good quality and durable, it just isn't enough for the Cayenne. The 955/957 is notorious for having cooling issues. Just driving down the road on a hot day can overheat the engine and off-roading and towing/hauling is much harder on the cooling system. On top of that, these SUVs are 15-20 years old now. Those still running the original radiator have definitely lost some cooling efficiency due to bend/damaged fins and tube clogging. Needless to say, CSF had a lot of issues to address while designing this new radiator.This Part Fits: Year Make Model Submodel 2007-2010 Audi Q7 Base 2007-2015 Audi Q7 Premium 2011-2015 Audi Q7 Premium Plus 2010-2015 Audi Q7 Prestige 2009-2010 Audi Q7 TDI 2011-2015 Audi Q7 TDI Premium 2011-2015 Audi Q7 TDI Premium Plus 2011-2015 Audi Q7 TDI Prestige 2004-2006,2008-2010 Porsche Cayenne Base 2008-2010 Porsche Cayenne GTS 2003-2006,2008-2010 Porsche Cayenne S 2010 Porsche Cayenne S Transsyberia 2003-2006,2008-2010 Porsche Cayenne Turbo 2006,2009-2010 Porsche Cayenne Turbo S 2005-2009 Volkswagen Touareg Base 2006-2010 Volkswagen Touareg TDI 2004 Volkswagen Touareg V6 2004 Volkswagen Touareg V8 2010 Volkswagen Touareg VR6

CSF originally designed the BMW S63 Charge-Air-Coolers for the F9X M5/M6. Over five hundred of these Intercoolers kits have been sold with many of them on 1000+ hp builds. Due to their popularity and success, CSF has received many requests to have a set made to fit the X5M and X6M. CSF worked with Steve Dinan's Carbahn to develop the mounting hardware needed to use these coolers. The result - a true plug-and-play system requiring no modifications to install that will take your M SUV to a whole new level.This Part Fits: Year Make Model Submodel 2020-2023 BMW X5 M 2020,2024 BMW X5 M Competition 2019-2023 BMW X6 M 2020-2021,2024 BMW X6 M Competition 2023-2024 BMW XM Base 2024 BMW XM Label

With data collected by development partners and race teams, CSF was able to design the ideal High-Performance replacement. The CSF radiator features the latest 5mm fin technology. These fins significantly increase the heat exchange surface area improving overall cooling efficiency and recovery while still maintaining good airflow. The core is much larger than the factory featuring 2-Row 42mm aluminum core. This both increases the fluid capacity of the radiator, and improves the cores ability to dissipate heat. CSF's Exclusive B-Tube Technology increases the heat transfer by approximately 15% over regular oval welded tubes. In addition, the super-efficient multi-louvered fins maximize airflow through the core for the best possible performance. The TIG-Welded 100% All Aluminum construction increases the overall strength of the radiator. This improves durability and longevity so you can be confident it will hold up to hard driving conditions.

CSF's core technology is also more resistant to heat soak compared to the OEM plate-type intercooler core. Not only is the core proven to lower IATs, but also maintains a more consistent lower average temperature - this is ideal for achieving optimal performance on vehicles with larger/upgraded turbochargers as well as maintaining maximum efficiency during racing or demanding driving conditions with repeated pulls such as at the drag strip or half-mile events. Performance testing resulted in lower outlet air temperatures from the CSF Intercoolers, showing almost no increase in intake air temperatures during the entire course of the dyno pull.This Part Fits: Year Make Model Submodel 2018-2022 McLaren 720S Base 2019-2022 McLaren 720S Spider 2021-2022 McLaren 765LT Base

CSF understands Porsche purists want to keep an OEM look even when upgrading the performance and reliability of their 914s. This was a driving factor behind many of the cosmetic features of the oil cooler. The top of the cooler is stamped with the OE Part Number just below the CSF logo. In addition, the cooler comes in a Titanium color Thermal Heat Dispersion Cerakote finish. This advanced finish is durable, improves heat dissipation, is anti-corrosive, and offers a very classy OEM+ look to the cooler. A modern upgrade over the original. No details were overlooked in the design of the CSF cooler. The curvature of the case matches the original precisely and includes all the fine details. The spark plug aperture matches up perfectly with the valve cover for a perfect fit. Built into the machined base plate are small but important details such as the raised mounting pads and strengthening ridges.This Part Fits: Year Make Model Submodel 1970-1971 Porsche 914 6

The 42mm 2-Row aluminum core increases the fluid capacity of the radiator by over 1 gallon (3.8L). A thicker core, second cooling row, and increased fluid capacity drastically improves the amount of heat the system can absorb and dissipate.

One of the goals of the CSF 911/930 Engine Oil Cooler was to have a single unit that could fit both older (65-71) and newer models (72-89). The solution may seem simple, but engineering the two upgraded stainless steel fittings so there was no oil flow restriction took some extra design work. CSF took some inspiration from the CSF 911/930 Turbo Fender Oil Cooler (CSF #8168) using a similarly designed "Widemouth Fitting". The threaded M30 "Widemouth Fitting" for the 65-71 models maintains the optimized inner diameter (ID) of the oil pipe to maximize flow through the oil system. The "Widemouth Fitting" offers 50% greater flow capacity over the OEM connection. The machined in-house Stainless Steel fittings offer increased strength and durability over the OEM Aluminum slip-on tube (72-89 models) and threaded M30 fitting (65-71 models). Both OEM connections are common sources of leaks. CSF also includes two high quality copper crush washers to offer the best possible seal and prevent any leaks.This Part Fits: Year Make Model Submodel 1965-1968,1974 Porsche 911 Base 1974-1975,1984-1989 Porsche 911 Carrera 1989 Porsche 911 Carrera 4 1969-1973 Porsche 911 E 1968 Porsche 911 L 1967-1977 Porsche 911 S 1978-1983 Porsche 911 SC 1989 Porsche 911 Speedster 1969-1973 Porsche 911 T 1976-1977,1986-1989 Porsche 911 Turbo Carrera 1978-1979 Porsche 930 Turbo

CSF is quite familiar with GM performance vehicles so creating a high-performance radiator for the C6 Corvette made a lot of sense. Also given the age of the C6, there are a lot of owners ready to upgrade or looking to replace their original radiators. The goal was to create a model that could fit all of the C6 Corvette trims and work with the majority of upgrades and modifications. CSF teamed up with A&A Corvette to develop this radiator. As experts exclusively developing products for Corvettes for over 20 years, they were the perfect R&D Partner for this radiator. This new design coupled with a core that has 193% more volume than the factory radiator offers a massive upgrade in cooling capacity. The CSF Radiator also offers the best value of any aftermarket radiator coming in hundreds of dollars less than competitors.This Part Fits: Year Make Model Submodel 2013 Chevrolet Corvette 427 2008 Chevrolet Corvette 427 Limited Edition Z06 2005-2013 Chevrolet Corvette Base 2010-2013 Chevrolet Corvette Grand Sport 2006-2013 Chevrolet Corvette Z06 2011 Chevrolet Corvette Z06 Carbon

The CSF N55 Intercooler's Stepped Core Design maximizes surface area contact and internal intake air-flow volume. The Rounded Front Face Bar/Plate Design optimizes airflow through the core and is a true "Drop-in Fit" Plug-and-Play Design. In testing the CSF Intercooler showed Intake Air Temperatures (IATs) that were 38 deg F (21 deg C) lower than factory after just 3 consecutive pulls from 4k RPM to 5.8K RPM. In that test, the CSF Intercooler maintained stable IATs. While most intercoolers don't offer immediate performance gains without increasing boost pressure, the CSF Intercooler shows an increase of 15-20hp on stock N55 Powered BMW's and 25+hp on modified examples.This Part Fits: Year Make Model Submodel 2013-2018 BMW 320i Base 2013-2018 BMW 320i xDrive Base 2012-2015 BMW 335i Base 2014-2016 BMW 335i GT xDrive Base 2012-2015 BMW 335i xDrive Base 2014-2016 BMW 435i Base 2015-2016 BMW 435i Gran Coupe Base 2014-2016 BMW 435i xDrive Base 2015-2016 BMW 435i xDrive Gran Coupe Base 2013-2015 BMW ActiveHybrid 3 Base 2016-2018 BMW M2 Base 2014-2016 BMW M235i Base 2015-2016 BMW M235i xDrive Base

CSF has over 5 decades of experience manufacturing radiators. So when it comes to keeping your engine cool and your E9X/E8X running at its best, a CSF High-Performance All-Aluminum Radiator is the obvious choice. Designed to perform on the street or at the track, a performance radiator is a must-have for both high horsepower builds as well as race vehicles which need added cooling performance in motorsports environments. This radiator features a 2-Row core with CSF's exclusive B-Tube Technology: Unlike a regular oval shape "O" type radiator tube, CSF uses a specially engineered tube in the shape of a "B". These "B-tubes" are carefully formed and then brazed over the seam to seal. CSF is able to use thinner and lighter aluminum material (with better cooling efficiency) because this design is actually stronger than normal "O" shape tubes that are welded. The design (inlet in the middle of the tube that is seam brazed) increases the heat transfer surface area of the tubes by approximately 15% over regular tubes - producing the efficiency of two smaller tubes vs. one large tube within the same space criteria. With "B-tubes" you are able to get "dual liquid laminar flow". CSF also uses ultra efficient multi louvered fins that are carefully and precisely aligned to maximize airflow through each radiator core. Fin specifications are carefully measured and calculated for each application, and tested for maximum heat rejection efficiency in our wind-tunnel lab.This Part Fits: Year Make Model Submodel 2008-2013 BMW 128i Base 2006 BMW 325i Base 2006 BMW 325xi Base 2007-2013 BMW 328i Base 2009-2013 BMW 328i xDrive Base 2007-2008 BMW 328xi Base 2006 BMW 330i Base 2006 BMW 330xi Base 2009-2010 BMW Z4 sDrive30i 2009-2010 BMW Z4 sDrive35i

The 2-Row 42mm aluminum core not only increases the fluid capacity of the radiator, but also improves the cores ability to dissipate heat. CSF's Exclusive B-Tube Technology increases the heat transfer by approximately 15% over regular oval welded tubes found on many other aluminum radiators. Additionally, the super-efficient multi-louvered fins maximize airflow through the core for the best possible performance. The end tanks are made from high grade aluminum and TIG welded to the core for extra strength. In contrast, the OEM crimped onto plastic end tank design is much weaker and creates a weak point where failure is more likely. Because the CSF radiator is designed as a true plug-and-play drop-in fit application, installation requires absolutely no modifications, trimming, or cutting. CSF even includes pre-cut double sided adhesive foam strips to help seal the fan shroud against the radiator. This improves airflow efficiency off the fan. In addition, the CSF radiator features a built-in transmission fluid cooler. The transmission cooler is a heavy-duty high-performance 5 plate design that connects to the OEM hoses. This upgraded built in cooler is great dealing with the added heat and stress from towing, low gear crawling, and vehicles equipped with oversized tires. While plenty of people understand the impacts of oversized tires, it is always good to provide additional information. By increasing the diameter of your tires, you are reducing the effective gear ratio. This means the engine and transmission have to work harder to move the tires. Obviously this will end up generating excess heat, and the CSF radiator is designed to handle it.This Part Fits: Year Make Model Submodel 1996-2001 Toyota 4Runner Base 1996-2002 Toyota 4Runner Limited 1996-2002 Toyota 4Runner SR5

The OEM intercooler is made from plastic end tanks that are crimped onto an aluminum tube/fin core that is 4 inches thick (105mm core width) and is 5 inches in height (127mm). This may be enough to keep IAT's in check on a completely unmodified / stock vehicle, but once users to start increase power through bolt-on modifications, tuning, and built engines, the OEM intercooler will become the Achilles Heel of the system with IAT's skyrocketing out of the optimal range and drastically lowering the performance capabilities of the vehicle. Enter CSF with their stepped core design, bar/plate high performance N54 intercooler. This "drop-in fit" intercooler, which requires no modifications to install, has a bottom / larger section that is 5.5in thick (140mm) with a front face that is massive 8.25in tall (210mm). Made from CSF's industry exclusive rounded bar/plate core design. The rounded front face of the cooling bars allows for better airflow into the core. Airflow hits the core surface, and rather than scattering like it does with hitting the face of a flat bar that all competing products have, it travels around the face of the round bar and into core for much better performance than both the OEM design (flat face) and all other aftermarket competitors (all have flat face tubes or bars). A huge improvement over the OEM unit, and enough to handle even the most advanced N54 engine builds.
