Top Mount Oil Cooler Kit

The B-Line Motorsports Top Mount Oil Cooler Kit is engineered to provide a robust solution for managing high engine oil temperatures in Subaru STI vehicles from 2015 to 2020. As the original developers of top mount oil coolers for WRX and STI models, B-Line Motorsports brings their expertise to this updated kit. The kit features a high-capacity, 25-row oil cooler designed for maximum efficiency. It utilizes durable, double-braided -10AN aircraft quality hoses with a stainless steel inner braid and a protective nylon outer braid for extreme heat resistance. A high-flow aluminum thermostatic oil filter sandwich plate adapter, calibrated to engage at 185°F (85°C), ensures optimal oil temperature regulation. The kit also includes vehicle-specific, B-Line Motorsports designed and manufactured aluminum mounting brackets and all necessary installation hardware. The kit is noted to fit with most aftermarket headers and charge piping. However, installation with certain aftermarket components may require an additional spacer for proper clearance. This top mount oil cooler kit can achieve temperature drops of up to 35°F (1.7°C), significantly enhancing the longevity and performance of your STI's engine under demanding conditions.
