The Yahua Performance Oil Filter Housing is beautifully over-engineered in customary Yahua Performance fashion to give an exquisite feel and exceptional product experience. BMW equipped their cars with a plastic oil filter housing which is fragile to say the least and is often cracked when removing and replacing, which in turn can result in oil leaks. We have improved on the original design and have produced this part in billet aluminium which is very light and durable and then tastefully finished with a polished anodised dark anthracite coating. Fitting is straight forward and best done in conjunction with an Oil and Filter change. Just remove the existing housing, remove the rubber O-ring, fit onto your new housing, and fit back in place. This will fit the following engines: BMW N20 BMW N52 BMW N54 BMW N55 BMW S55 Please note if the part is under excessive heat for prolonged periods of time, it can affect the overall finish which is unavoidable with anodised aluminium products.
