Trusted by professional race teams around the globe, Improved Racing's thermostats have proven highly reliable, are backed by a lifetime warranty, and are made in the USA. Option to Use the Factory Oil Cooler and Lines The optional factory oil line adapter allows you to use the factory oil cooler lines for a simple, plug-and-play installation. For maximum performance, the factory oil cooler and lines may be replaced with an aftermarket cooler and AN lines using the AN adapter fittings (-10AN line size is recommended). Please note that some applications, such as most BMW SUV's, use a water-to-oil heat exchangers.

Rally Road Productions, Inc. is a team supported by a group of people with great abilities in their area of expertise. From the "web guy" and driving instructor friends, to owners of various machine shops, they have surrounded ourselves with people that can be trusted to create and manufacture quality products. This is the key to ensuring everything that they sell will perform as it was intended. The goal is to increase customer satisfaction and make the customization or performance enhancement of your vehicle a more enjoyable venture.

This oil cooler system is race tested and proven to outflow the euro M3 oil filter housing. Additionally, this particular system uses a sealing mechanism to direct the oil flow through the cooler lines and then through the oil filter. Other cooler caps do not provide this seal and therefore the external oil coolers and lines act as a "balloon". The lines and cooler are pressurized, but oil does not flow through them. Flowing oil means it is being cooled and not just acting as an external reservoir.

Flow testing reveals that the oil cooler cap will outflow the Euro M3 Oil Filter Housing by more than 80% at the same, pressure, RPM, and oil temperature. In the upper RPM range, there is nearly a 100% improvement in flow from the RallyRoad oil cooler cap when compared to the Euro M3 oil filter housing. This is a massive improvement over OE and is a worthwhile upgrade, especially in engines that see severe duty.

Features:

-8AN o-ring ports to provide a leak free fitting without the use of Teflon tape or sealant used by other oil cooler caps.
Viton o-rings are used throughout to maintain function and sealing in a high-temperature oil environment.
Use of the stock filter cap bolt to reduce cost and simplify installation.
An internal sealing mechanism to direct oil flow through the oil cooler and through the filter.
1/8" NPT side port for external oil pressure gauge.

Kit Includes:

Oil filter cap with fittings
Oil filter sealing ring
BMW MANN Oil Filter and gasket
