MMX Oil Thermostat Lid and Caps – BMW M4

Manufactured from T6061 billet aluminium, our thermostat 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, a must-have for those that like their engine bay looking at its best.

Please Note:

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.
