An internal combustion engine like the N55 engine, imparts high shear forces on the motor oil, which is sandwiched between two rotating or sliding forces under load and heat.  \"Shearing\" is when the molecular structure is essentially torn apart by these mechanical shear forces.  Lower your operating oil temperature will greatly reduce this.  Thus your motor oil is in better shape to protect the bearings in your car's engine, thus improving longevity.\u003c\/p\u003e\n\u003cp\u003eThe M235i\/335i\/435i\/M2 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.\u003cspan class=\"partdesc\"\u003e  The Sports Series Oil Cooler system features a large \u003c\/span\u003e\u003cspan class=\"partdesc\"\u003e11\"x8\"x2\" (280mmx203mmx51mm) oil cooler \u003c\/span\u003e\u003cspan class=\"partdesc\"\u003ewith 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!\u003c\/span\u003e\u003cspan class=\"partdesc\"\u003e \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan class=\"partdesc\"\u003eThe Sports Series Oil Cooler mounts to its own box enclosure.  \u003c\/span\u003eThis style box was developed on our 135i Time Attack race car and is brought here to our new F30 applications  \u003cspan\u003eLouvers 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. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eEverything 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 Stainless Steel Braided Lines are used throughout the kit.  \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch4\u003e\u003cb\u003eFeatures\u003c\/b\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eReduces the high oil temperatures that N55 engine produces which helps reduce oil breakdown, improving the longevity of your car!\u003c\/li\u003e\n\u003cli\u003eLarge 9\"x8\"x2\" (11\"x8\"x2\" with end tanks) Oil Coolers.  Factory stock oil cooler 8.75\"x4.75\"x1\"\u003c\/li\u003e\n\u003cli\u003eOver \u003cstrong\u003e350%\u003c\/strong\u003e larger capacity than the factory oil cooler!!!\u003c\/li\u003e\n\u003cli\u003eSports Oil Cooler has a total of 144 cubic inches of core!  Factory oil cooler has 41 cubic inches.\u003c\/li\u003e\n\u003cli\u003eAvailable with no finish (silver) or \u003cspan class=\"partdesc\"\u003eType III Hard Black \u003cspan class=\"FAAdLink\"\u003eAnodizing\u003c\/span\u003e (for stealth).

Another added benefit of the Type III Hard Anodising is that it makes the oil cooler fins harder and stronger, which makes it less prone to getting bent\/damaged from road debris like rocks etc... We opted for the Type III Hard Anodising over the Type II color anodising which is only asthetics for this purpose only (even though it cost us considerably more to anodize Type III than Type II). We started using the Type III Hard Anodised Black finish on our rally car customer's FMICs years ago.  Rally cars go through tremendous amounts of abuse and it was quite common to take hits on the intercooler from debris on the course.  In fact after 1 event, we would often see a large portion of the intercooler fins bent (killing efficiency) and fixing them after each event was quite tedious.  After the Type III Hard Anodising, we notice a big difference as there was considerably less damage.  Even after hits and even accidents, the FMIC could take more abuse than before.  Testing has shown \u003cstrong\u003eno\u003c\/strong\u003e noticeable ill-effect from the Type III Hard Anodising on performance (regular spray paint etc... has shown ill-effects on performance).  Eventually, we started utilising the same Type III Hard Anodise Black on our street cars and FMIC applications.  It's only natural we would offer the same finish for our oil coolers. \u003cbr\u003e  \u003cbr\u003e\u003cspan\u003e\u003cstrong\u003eKit Options:\u003c\/strong\u003e\u003c\/span\u003e\n\u003cp\u003e\u003cspan class=\"partdesc\"\u003eWhen the oil cooler box enclosures are used in conjunction with our 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 aluminium.  These are model and bumper specific so make sure you order the correct shroud kit.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eCompatibility\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cdiv\u003e\u003cspan class=\"bigblack\"\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cp\u003eBMW F chassis M2, M135i, M235i, 335i \u0026amp;
