Description

The Mishimoto oil cooler line is a direct-fit replacement for the 2004-2008 Mazda RX-8. This kit includes the stainless steel line, M18 banjo bolts, and oil seals for installation.

The high-winding rotary engine of the Mazda RX-8 can lead to high oil temperatures, especially during track use. Stock rubber oil lines and steel fittings can degrade over time due to corrosion, particularly in areas exposed to dirt and road salt.
