Experience the ultimate performance upgrade with our high performance intercooler for the BMW M135i and M235i. This impressive intercooler sets new standards and is specifically designed to meet the high demands of the big tuning levels. With intecooler core dimensions of 510mm x 345mm x 180mm (stepped 23.56L), our intercooler offers a 165% larger flow area and a whopping 223% more charge air volume than the original intercooler. The high-quality Competition high-performance core with internal turbulators ensures optimum cooling performance. Despite its imposing size, the entire intercooler weighs just 13.8 kg, highlighting its efficiency and lightweight construction. The cast aluminum end boxes of the charge air cooler were optimized using flow analyses in the CFD system to ensure outstanding cooling properties with minimal backpressure. Our kit EVO3 eliminates the original click connections and expands the connection diameters to Ø65mm at the inlet and Ø76mm at the outlet. Additionally, the kit includes reinforced silicone tubing and an aluminum charge air tube in Ø76mm. The result is unmatched cooling performance with a significant increase in power. Our intercoolers are all coated with a high-quality anti-corrosion coating, which not only ensures protection against environmental influences, but also has excellent heat conduction properties. This ensures long-lasting and optimal cooling. Our intercooler kit is supplied complete and is ready for installation. Replacing it with the stock parts is easy thanks to the modified crossmember that comes with it. Due to the extreme size of the intercooler, minor adjustments to the radiator support may be required. Our high performance intercooler has been tested under extreme conditions and is pressure stable up to 6 bar. Each of our products is subject to constant qualitative monitoring to ensure the highest reliability. This intercooler is the perfect choice for racing and lets your vehicle set new standards in power and performance.
