Description

The STILLEN transmission cooler kit is a high-performance solution for managing automatic transmission temperatures on the street and at the strip. By increasing total fluid capacity and improving heat dissipation, this kit helps prevent the viscosity breakdown and internal transmission strain associated with high fluid temperatures, promoting long-term reliability and smoother operation. It is specifically designed for use with automatic transmission configurations and is ideally suited for vehicles already equipped with a STILLEN 370Z front bumper fascia. The complete package includes all necessary adapters, hoses, fittings, and brackets required for a direct-fit installation. This kit is compatible with 2008-2013 Infiniti G37, 2015 Infiniti Q40, 2014-2015 Infiniti Q50 (3.5L and 3.7L), 2014-2015 Infiniti Q60, and 2009-2018 Nissan 370Z models equipped with an automatic transmission. Note that this system is intended exclusively for automatic transmissions.
