The 1st models of this new “O” Series is for the Subaru platform: 02-07 STI/WRX (CSF #3076O). This application was developed alongside industry leading Subaru engine builders & race tuners, LIC Motorsports from Northern California. CSF also reached out to one of their closest race teams, Subaru tuners, and dealers; Snail Performance, to help with fitment and performance testing in the hot Arizona desert they are regionally located in.
Technical Specs:
- The radiator utilizes a 2-row 42mm core that feature 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-liquid plate-type oil cooler built into the bottom endtank. A liquid-to-liquid cooler is much more efficient than a conventional air-oil cooler. CSF has lab tested these in their ISO certified in-house 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 endtank, 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 engine 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.
- The kit does not include hose and fittings to go between the sandwich plate and radiator. Touge Tuning can supply the correct fittings, hose and fire sleeve needed to complete the kit.
