The CSF 3076O combines a high-performance all-aluminum radiator and an engine oil cooler in one drop-in unit for manual transmission applications. The core is a 2-row 42mm design with CSF's exclusive B-tube technology and 6.5mm multi-louvered fins, and a robust 4-plate liquid-to-oil cooler is built into the bottom end tank so engine oil temperature is regulated by the cooling system thermostat. The kit includes two -10AN male fittings, forged 90 degree -10AN fittings and an M20 x 1.5 filter sandwich plate; oil lines are not included and must be sourced separately. Installation requires an additional 1/4 to 1/2 quart of engine oil, and the radiator ships with a CSF 1.4 bar (20 psi) cap and a 1-hour mirror hand polish. On 2006 and 2007 WRX models the factory oil cooler and exhaust manifold make for a tighter fit, which may require removing the factory oil cooler and capping its coolant line or running aftermarket headers.
