Oil Cooler Stainless Steel Braided Hose Set

Hoses comes fully assembled, it replaces the 8 original factory oil cooler hoses with just 3 hoses.
1) engine out-to-cooler, 2) cooler-to-cooler, and 3) cooler-to-engine in.
Eliminating possible leakage areas during racing and high output applications.
Each line is pressure tested at the end of the assembly process.

Unlike earlier rotary applications, replacement of the oil lines on the RX-8 application requires substantial labor effort and is best undertaken when the engine has been removed from the vehicle. Although more challenging due to limited access, this project can be undertaken with engine in the vehicle, just allow adequate time to complete the process. With the engine in the vehicle this is an involved project that can’t be rushed! Shipped complete with all required oil lines, oil cooler and engine adaptors, bracket hardware, protective end caps, and fully detailed installation instructions.

Idemitsu Racing Engine Oil
Idemitsu Rotary Engine Oil is the only oil specifically designed to be used in the rotary engine. As the developer of the engine oil for the winning 1991 LeMans Mazda 787B and a long time supplier of vital lubricants to Mazda, Idemitsu has intimate knowledge of the requirements of rotary engines.

Idemitsu Rotary Premix Idemitsu Racing Rotary Fuel Lube (Premix) - Synthetic Blend

Inherently with many rotary engines, the entirety of the rotor and housing are not being sufficiently lubricated, resulting in premature wear or damage. In order to increase lubrication within the engine, Idemitsu developed Idemitsu Rotary Premix. At 1/2 oz per gallon of fuel, it is a cost effective way to lubricate more of your engine and prevent premature catastrophic damage.
A special blend of base oils reduces deposits and subsequent exhaust port clogging. As a result, your rotary will maintain the power at which it was designed. Special detergent/dispersant additives keep your fuel injectors clean to reduce maintenance. Provides additional lubrication for apex and side seals to increase seal life and increase the efficiency of the engine. Special additives allow for better sealing of the chamber, creating greater efficiency and more power.

Do NOT use with ethanol or ethanol based fuels!

Available by the quart or by the 12 qt case
