CSF Radiators “O” Series All Aluminum Race-Spec Radiators w/ Built in Oil Coolers 2002-2007 Subaru STI/WRX

CSF Racing & High-Performance radiators are extremely proud of their innovative “O” Series radiators. They brought to market the first all aluminum race-spec radiator with a built-in oil cooler! Starting with options for the Subaru platform: 02-07 STI/WRX (CSF #3076O). Sparing no expense, CSF’s kit includes a machined thermostatic sandwich plate made by Greddy and forged right angle -10 fittings made by BAT.

Technical Specs:

• These radiators utilize a 2-row 42mm core that features CSF’s exclusive B-tube technology, as well as an ultra-efficient 6.5mm multi-louvered fin for maximum surface area contact, heat dissipation, and extreme performance capabilities.
• Equipped with an all-aluminum racing style drain plug for quick and reliable fluid changes
• CSF 1.4 Bar (20 psi) radiator cap
• Engineered and designed to be a complete “drop-in fit” install. Works with all the OEM brackets, fittings, AC condenser, hoses, and fan shrouds (only minor trimming needed at fitting locations)
• Featuring a robust 4-plate liquid-to-oil plate-type oil cooler built into the bottom end tank. A liquid-to-oil cooler is much more efficient than a conventional air-oil cooler. Lab tested in CSF”s ISO certified in-house lab testing facility to reject heat better and at a faster rate than a 10-row air-to-oil cooler. In addition, by being placed in the bottom end tank, the oil temperature is regulated by the thermostat of the cooling system. Never have to worry about operating temperatures not warming up fast enough in cold weather climates.
• Complete with 2 AN-10 male fittings and is compatible with many popular aftermarket engines and exhaust manifolds.
• This kit comes complete with a machined thermostatic sandwich plate made by Greddy and forged right angle -10 fittings made by BAT.
• Topped off with the industry’s finest 1-hour hand polish “mirror finish” for a look that matches the performance.
