BMW Oil Coolers & Oil Cooler Parts for BMW 3 Series E46 (1999-2005)

Clear BMW chassis
The condition and state of your oil can make or break your day at the track. Oil is working best during a certain temperature range and when exceeded the protective properties of oil will break down. This is especially critical with older, dirty oil. Newer cars with high underhood temperatures are even more at risk. Aside from frequent oil changes and more capacity the best way to keep healthy oil flowing through your engine vitals is with an oil cooler. We offer track-developed oil cooler kits and other accessories aimed at reducing oil temps or making your current setup work safely and more efficiently. An oil cooler will not make your car faster or handle better. It's simply excellent preventative action to avoid costly troubles in the future.

Made in the USA NEW, updated design allows for more applications! The TMS Oil Cooler Fitting kit allows much more flexibility in the routing of oil cooler lines. Standard oil coolers utilize "hard lines" which can cause fitment issues for cars with superchargers, Accusumps, or other aftermarket performance parts. Our kit replaces the oil cooler hard lines with two TMS engineered -10 AN fittings, mounting bracket, and O-rings. Flexible braided hoses can then be run to the oil cooler which eliminates routing issues from supercharges, intakes, and other components. The brackets are CNC machined stainless steel and the -10 AN fittings are lightweight aluminum.

NEW REVISED Kit fits E36 Euro oil filter housing, E36 Euro oil cooler, E46 M3 stock oil filter housing, E46 M3 stock oil cooler , and works great with aftermarket oil coolers.

This is the sealing o-ring used for many oil cooler kits on various BMW models. They're also a prime source for oil leaks because the o-ring gets 'flat' or shrinks or becomes damaged. These are usually easy to change though which puts an end to annoying small oil leaks.

In German, Rein means Pure. In the automotive industry the Rein name has quickly come to represent quality. With fitments for some of the worldaEURtms finest automobiles including BMW and Mini and guaranteed OE quality, Rein is a name you can trust.

Priced per o-ring but most cars have 4 to replace.

The stock oil cooler on the E46 M3 is simply not up to the task, with oil temps rising quickly on track days. We have solved that problem by assembling this kit with a much larger Fluidyne oil cooler, our own special-length oil cooler lines, and the Turner Motorsport Oil Line Fitting Kit. The Fluidyne oil cooler has more surface area and holds more oil than the original. This not only ensures the oil is cooled better but also that hot oil is circulated through the system less often (less heatsoak of the oil). With this kit on our SCCA T2 M3 we never had oil temp issues, even after two seasons of National and Runoff races. The cooler can fit in the factory location for a safe and clean appearance, however, brackets must be fabricated by your installer. The lines are custom made to our spec with extra strength braided steel with a Teflon outer coating and -10 AN fittings. The lines attach to the stock oil filter housing with our Oil Line Fitting Kit and o-rings are included. The length of the lines also makes them compatible with most supercharger kits (with custom brackets you can mount the oil cooler so that nothing on the cooler or the supercharger needs to be modified for fitment).

Fitment note: due to the various uses and locations available, brackets are not included with the oil cooler. Hanger brackets will need to be fabricated to mount the oil cooler to the car.

This item fits the following BMWs:
2001-2006 E46 BMW M3
