Subaru WRX / STi Top Mount Oil Cooler `01-`07


B-Line Motorsports has developed a top mounted oil cooler kit that essentially mounts in the same location as the factory intercooler. Utilizing the dead space and scoop created by installing a front mount intercooler; our oil cooler can improve the vehicle’s overall cooling capabilities. The advantage of installing this top mounted oil cooler is the fact that the radiator and intercooler will work more efficiently by having one less object restricting air flow. Many hours were expended in the design of the mounting brackets so that the final product would incorporate the factory mounting holes when attaching the oil cooler to the motor. This type of installation allows the oil cooler to move in conjunction with the motor, resulting in a long life span. B-Line Motorsports has also wrapped certain portions of the oil lines that are near extreme heat, such as the turbo and exhaust manifold, with a lightweight sleeving that withstands radiant heat over 800°F. In testing, oil temperatures were measured to drop 30°F to 40°F. Making this kit the most effective and most efficient kit on the market!
