Mishimoto Primary Replacement Oil Line for 2004-2008 Mazda RX-8 (MMSBH-RX8-04)

Fits 2004-2008 Mazda RX-8 models across all trims including Base, Shinka, Sport, Touring, Grand Touring, and 40th Anniversary Edition.

The high-revving rotary engine in the Mazda RX-8 generates significant heat, relying on dual oil coolers to maintain safe operating temperatures during spirited driving. Over time, the factory rubber lines and steel fittings—specifically the primary line located on the left-hand side near the front suspension—are prone to severe corrosion and degradation from road salt and debris. The Mishimoto Primary Replacement Oil Line provides a durable, corrosion-resistant solution to prevent oil leaks and protect your engine.

This direct-fit replacement features a premade braided stainless steel line paired with aluminum M18 to -10AN banjo fittings. Unlike the OE components, these materials are engineered to resist high-pressure fatigue and environmental wear. The kit is designed for a straightforward bolt-on installation with no cutting or permanent vehicle modifications required.
