Recommended by The Experts: - Sean Singh / Sr. Mod Expert / 2007 E92 BMW 335i ""I love my 335i, it is an amazing car. I love driving it, it is everything I look for in a car. Sometimes when I used to drive aggressively and having fun, I would look at my cluster and there is a bright RED error, my engine is close to overheating. Every time I am having a lot of fun this happens! I am tired of the puny oil coolers that BMW in their infinite wisdom installed in this performance ultimate driving machine. I can't even drive it like a performance car without risking engine failure or worse. I knew I had to fix this problem. I started doing some research and talked to some experts and I am glad I found this Evolution Racewerks Oil Cooler Kit. It came with everything I needed to install it. The instructions were detailed, the technical support is amazing and I really couldn't ask for more. And they look amazing, the aggressive look you get without the bumper is just awesome. I have pushed my car to the limit now, the temperature stays consistent and I don't have anymore overheating issues. Now when I go out and drive my car aggressively I don't have to always worry about my temperature gauge, I can focus on the perfect shifts and just have fun! I would recommend this mod for anybody who likes to drive their car aggressively or just wants to extend the life of their engine. ""

After 3 years of development, they're finally ready. Introducing Evolution Racewerks Competition Oil Cooler System! 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!

Competition Series Oil Cooler

The 135i/335i comes from the factory with a small oil cooler with a core size of 8.75""x4.75""x1"" (222mmx121mmx26mm) which comes out to 41 cubic inches of core.  The Competition Oil Cooler system features a pair of massive 11""x8""x2"" (280mmx203mmx51mm) oil coolers with a core size of 9""x8""x2"" (229mmx203mmx51mm).  The Competition Oil Cooler comes out to 144 cubic inches  of core which is 3.5 times larger than the factory unit each! 

The Competition 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 ER had to replace the oil coolers on Evolution Racewerks' Time Attack 135i.  Thus, instead of a big hole for airflow to flow through, we 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.

Everything needed to install is included with the kits.  No low quality, cheap fittings and lines made overseas used here.  High quality Goodrich anodized black AN fittings and high end Goodrich Nylon Braided Lines are used throughout the kit.  These high end Goodrich Nylon Braided lines are the new thing to use for oil lines as they have many advantages and no disadvantages (other than higher price) than traditional stainless steel braided lines.  The main advantage is that they are lightweight.  Nylon is considerably lighter than stainless steel.  The second advantage is that Nylon Braided Lines are stronger than traditional stainless steel lines.  Third, is that Nylon Braided Lines do not fray.  Stainless steel braided lines will start to fray and those who are familiar with stainless steel braided lines know what we're talking about.  The stainless steel mesh in the lines start to ""fray"" or break and thus you get poked with the broken ends.  Saves a lot of bloody fingers.  Fourth, they are abrasive resistant.  Since stainless steel lines will act like a saw when it comes in contact with anything and will eventually cut anything it contacts whereas the Nylon braided lines are soft and pretty much won't ever do it.  Fifth, heat resistance.  Nylon Braided lines can withstand more heat and retain the heat inside the line better.  Stainless steel lines tends to release the heat inside the lines, thus when you touch the lines, they tend to be hot.  With all these advantages of the Nylon Braided Lines over stainless steel lines, it's the obvious choice for an Evolution Racewerks product.
