Evolution Racewerks Sports Oil Cooler for 2007-13 BMW 135i/335i [E82/E90/E92/E93] BM-COOL002PALU1

It's well known that the N54 and N55 engines runs very hot. Turbos that build a lot of heat and a small radiator play into why this engine runs so hot. A quick look at your gauge cluster on your dash after a few minutes of ""spirited"" driving, you'll notice oil temperatures over 250 degrees. Considering that most cars don't even exceed 230 degrees tells you quite a bit. As the oil reaches that temperature oil starts to lose viscosity and break down. Increasing the size and efficiency of your oil cooler will not only increase your engines life span but also giving you more power!

The Sports Series Oil Cooler mounts to its own box enclosure. Louvers on the backside of the box enclosure ensures airflow through the oil cooler while protecting the oil cooler from road debris, especially debris kicked up from the front tires. During initial testing, Evolution Racewerks' box enclosure had a big window (open hole) in the back for airflow. However, throughout the race season, it took so much abuse from rocks, tire and other debris kicked up from the front tires that Evolution Racewerks had to replace the oil coolers on Evolution Racewerks' Time Attack 135i. Thus, instead of a big hole for airflow to flow through, Evolution Racewerks used louvers instead to protect the back side of the oil cooler. This effectively solved the issue without any affect on performance. Oil temperatures as well as oil temperature deltas stayed the same.

When the oil cooler box enclosures are used in conjunction with Evolution Racewerks' optional ducting shroud kits, the oil cooler box enclosure actually seals and forces all the airflow captured by the ducting shrouds through the oil cooler cores. Improves the oil cooler's effectiveness and efficiency. The ducting shroud kits are available in aluminum or carbon fiber. These are model and bumper specific so make sure you order the correct shroud kit.

Please Note:

Be sure to check in your 335i came with a factory oil cooler. You can check this by looking in passenger side wheel well. If there is a louvered vent on the fender liner in front of the wheel your vehicle came with a factory oil cooler.

The very first 335i built in early 2006 did not come from the factory with an oil cooler. With the N54 engine running very hot, BMW quickly realized that this was a big mistake. An oil cooler was quickly added the next year. For those who do not have the factory oil cooler, you will need to convert your car's oil filter housing to a later model year that has external ports for an oil cooler. Evolution Racewerks are now offering these brand new genuine BMW parts to make the conversion. Parts included: Oil Filter Housing, Oil Cooler Thermostat housing, gaskets and hardware.
