Manufactured from T6061 billet aluminium, the MMR Performance Thermostat Cover dress up kit for the BMW N55,N54 and S55 engines offers a high-quality aesthetic update to the OE thermostat cover. Installation is extremely easy and the end result speaks for itself!
The billet covers are then anodised in our trademark MMR Deep Gloss Black for a beautiful finish. As a further option, if you are fitting an oil pressure sensor or oil temperature gauge you can select the optional extra cap with a 1/8NPT thread incorporated when you order.
By getting rid of the factory plastic parts, you'll also be avoiding the inevitable cracking and leaking that tends to develop as the car gets older and covers higher mileages. Peace of mind never looked so good.
As a nice option to add, the MMR Performance Thermostat Cover set can be ordered to include an oil pressure sensor or oil temperature gauge take off with a 1/8NPT thread kit for the BMW N55, N54 and S55 engines.
NOTE: If you are fitting an oil pressure sensor or oil temperature gauge please select the optional extra piece with a 1/8NPT thread from the drop down menu.
If these parts are exposed to excessive heat for prolonged periods of time, it can affect the overall finish which is unavoidable with anodised aluminium products.
