The MMR Performance catch can kit has been engineered for owners of F2x N55 M135i, M235i and M2 vehicles that want to ensure their engines are running at optimum performance, by removing unwanted oil from the PCV (Positive Crankcase Ventilation) system before it can be recirculated back into the intake. Higher mileage engines and those particularly that utilise direct-injection are known to suffer with sludge and carbon build-up on the backs of the inlet valves, but by removing the deposits through the catch can's filter and separation process, the intake air has less oil in it and therefore a higher ratio of oxygen is burnt, resulting in a cleaner, more reliable and better performing engine. As with all MMR components, our catch can kit has been designed to offer added performance, allow easy installation and enhanced aesthetics too. The T-6061 billet filter housing, anodised in our trademark MMR hue, is located on the inner wing using our precision made billet bracket for easy installation, whilst thanks to the bespoke race hoses and crimped race fittings, installation couldn't be any more straightforward - we've even replicated the more complex connector on the cam cover in billet aluminium! Checking the level for any oil removed from the intake system is easy thanks to the integral dipstick. A cap-head bolt mounted in the lower section of the catch can allows for easy draining, or if you prefer, the lower section itself can be easily unscrewed and removed. FEATURES Effectively prevents oil build-up in the intake system and intercooler walls Maintains optimum engine performance Easy installation with all supplied hardware included Race fittings and PTFE-lined hoses throughout Easy oil level checking and draining
