After more than 18 months of development and a $20k+ investment into the perfect oil cooling tube and fin combination, CSF has answered the call of Porsche enthusiasts around the world with the introduction of its state-of-the-art 911/930 Turbo right fender oil cooler. This oil cooler maintains the classic design for even the most discerning, concourse-winning restoration customer, but comes packed with innovative modern technologies, features, and high performance to also meet the demands of high horsepower builds with bigger engines, larger turbos, and standalone ECU management systems. Something that's never been done and now exclusively available from CSF.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 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

CSF has over 5 decades of experience manufacturing radiators. So when it comes to keeping your engine cool and your E30 M3 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 1988-1991 BMW M3 Base

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 1995-2004 Toyota Tacoma Base 1998 Toyota Tacoma DLX 1998-2000 Toyota Tacoma Limited 1998-2004 Toyota Tacoma Pre Runner 1995-2000 Toyota Tacoma SR5

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 2014-2016 BMW 228i Base 2015-2016 BMW 228i xDrive Base 2013-2018 BMW 320i Base 2013-2018 BMW 320i xDrive Base 2011-2016 BMW 328i Base 2011-2016 BMW 328i xDrive Base 2011-2015 BMW 335i Base 2014-2016 BMW 335i GT xDrive Base 2011-2015 BMW 335i xDrive Base 2014-2016 BMW 428i Base 2015-2016 BMW 428i Gran Coupe Base 2014-2016 BMW 428i xDrive Base 2015-2016 BMW 428i xDrive Gran Coupe 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 2014-2017 BMW i3 Base 2014-2017 BMW i3 Range Extender 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 F2X/F3X 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 2014-2016 BMW 228i Base 2015-2016 BMW 228i xDrive Base 2013-2018 BMW 320i Base 2013-2018 BMW 320i xDrive Base 2011-2016 BMW 328i Base 2011-2016 BMW 328i xDrive Base 2011-2015 BMW 335i Base 2014-2016 BMW 335i GT xDrive Base 2011-2015 BMW 335i xDrive Base 2014-2016 BMW 428i Base 2014-2016 BMW 428i xDrive Base 2014-2016 BMW 435i Base 2014-2016 BMW 435i xDrive Base 2014-2017 BMW i3 Base 2014-2017 BMW i3 Range Extender 2014-2016 BMW M235i Base 2015-2016 BMW M235i xDrive Base

The original OEM B58 heat exchanger is a 1-row unit that is 27mm thick. In comparison, CSF has used its industry-exclusive world's largest 2-row core (68mm) with CSF's B-Tube technology. A unique tank design allows the larger CSF core to still fit into the OEM cooling system housing. Another critical feature of the CSF BMW B58 high-performance heat exchanger is its unique triple-pass flow design. The water traveling through the upgraded heat exchanger flows through the radiator three times before exiting the cooler and flowing back into the manifold charge cooler. This ensures that the outlet water temperature of the heat exchanger is the absolute lowest it can be. The OEM design, as well as more expensive aftermarket designs, all have single-pass flow structures.This Part Fits: Year Make Model Submodel 2017-2021 BMW 230i Base 2017-2021 BMW 230i xDrive Base 2014-2018 BMW 320i Base 2016,2018 BMW 330e Base 2017 BMW 330e iPerformance 2017-2018 BMW 330i Base 2017-2018 BMW 330i GT xDrive Base 2017-2019 BMW 330i xDrive Base 2016-2018 BMW 340i Base 2017-2019 BMW 340i GT xDrive Base 2016-2018 BMW 340i xDrive Base 2017-2020 BMW 430i Base 2017-2020 BMW 430i xDrive Base 2017-2020 BMW 430i xDrive Gran Coupe Base 2017-2020 BMW 440i Base 2017-2020 BMW 440i Gran Coupe Base 2017-2020 BMW 440i xDrive Base 2017-2020 BMW 440i xDrive Gran Coupe Base 2017-2021 BMW M240i Base 2017-2021 BMW M240i xDrive Base

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
