VTT BMW Billet Coolant Reservoir Cap

VTT is proud to offer our billet replacement for the factory plastic Coolant Reservoir cap. This cap does away with the weak plastic cap while adding some pop, and color to your engine bay. These Coolant caps retain ALL of the factory provisions by simply allowing you to snap the factory pressure-relief into the new Billet Cap

We also designed these caps to complement our N5X Billet Oil caps, N5XBillet Oil filter housing caps, and Billet Power Steering cap and so all 4 will have the same design.

We offer these caps in 4 colors – Red, Black, Blue, and Clear.
