Evolution Racewerks Sport Series Oil Cooler 135i/335i

Basic Kits comes in a Black Finish

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 Sports Series Oil Cooler system features a large 11"x8"x2" (280mmx203mmx51mm) oil cooler with a core size of 9"x8"x2" (229mmx203mmx51mm).  The Sports Series Oil Cooler comes out to 144 cubic inches  of core which is 3.5 times larger than the factory unit each! 

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, our 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 we had to replace the oil coolers on our 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.
