Oil Cooler for BMW E36 (1992-1998) M3

Clear BMW chassis

Please ensure your correct model is selected

BMWs use an external oil cooler to regulate the temperature of engine oil and prevent a breakdown in viscosity and lubrication characteristics. If yours has suffered damage or developed a slight leak, make sure to replace it and keep the engine oil where it is supposed to be. Keeping this system properly serviced will significantly improve performance and increase engine life.

Made in the USA The TMS E36 Stage 2 Oil Cooler Line Upgrade Kit is an ideal alternative to the factory oil cooler lines, with multiple added benefits. In combination with our TMS AN-10 Oil Line Adaptor Kit (Part # TEN9910200), installing the TMS E36 Stage 2 Oil Cooler Line Upgrade saves you time and money. Unlike factory lines, the TMS E36 Stage 2 Oil Cooler Line Upgrade can work with vehicles equipped with superchargers or racing alternator pulleys. The TMS oil cooler lines now sit safely away from any moving parts like pulleys and serpentine belts. Our lines are made from HTP (High Temperature Polymer Braided), a synthetic line with multiple advantages over rubber or stainless lines.

We picked HTP lines for four reasons:
1) it insulates the oil from heat better than rubber or stainless lines,
2) the hose can hold a tighter bend radius without crimping or restricting oil flow, which makes routing the oil lines easier and more versatile,
3) the HTP line are less abrasive than stainless steel braided lines so they won�t rub through your factory power steering lines or any other rubber hose on the car,
4) weight savings � even if it is not much remember it all adds up.

Please Note, the following parts are required to install these lines:
� Euro oil filter housing
� Euro oil cooler and mounts
� (2) TMS AN-10 Oil Line Adaptor Kits (Part# TEN9910200)

The E36 Euro Spec Oil Cooler is exactly what it sounds like. E36 M3’s in Europe came equipped with an oil cooler that mounted under the radiator and was a popular upgrade for E36 owners in the US. Unfortunately, BMW discontinued the oil cooler and they have become harder and harder to find. BimmerWorld reached out to CSF to design a replacement unit that would fit exactly like the factory unit but perform even better. The original oil cooler used Tube and Fin construction. While this is acceptable for cooling performance, it is not a very robust design. CSF chose to go with a Bar and Plate construction to improve durability. While there is plenty of ground clearance, the cooler is low enough to see some potential abuse on the track. CSF wanted to offer that extra durability of a Bar and Plate cooler for track enthusiasts and those running their car on the lower side. The CSF Oil Cooler was designed to be a 1 to 1 replacement for the OEM unit in terms of fitment. This means it uses the same OE mounting points, hardware, and lines. For a Euro E36 M3 or US Z3M, the oil cooler will be a drop-in fit installation. E36 models that were not equipped with the oil cooler from the factory will need the BimmerWorld Euro Oil Cooler Bracket Kit which can attach to an OEM spec Radiator or the CSF #3054.

These are the Original BMW oil lines / tubing / hoses to connect the Euro M3 oil cooler to the Euro oil filter housing. These hoses can be used on any E36 6 cylinder (325i, 325is, 323is, 328i, 328is, and M3) to add the European oil cooler. Before ordering these lines, be sure you have all the parts required to do the installation -- including the Euro oil cooler bracket kit, the Euro oil cooler, and the modified oil filter housing. These lines give a factory appearance to the oil cooler retrofit which makes them perfect for otherwise stock cars. If you have a supercharger or track car and need something a little more special, you should get the lines from our Stage 2 Oil Cooler Kit.

This item fits the following BMWs:

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
