Product Details

Sourced from the Halo Car Audi R8 this coolant cap adds a unique styling touch that will give your engine bay a whole new character. Replace your blue coolant cap with this polished aluminum upgrade.

Often times, the coolant is not kept under enough pressure to keep it from boiling or expanding too much. This cap keeps all the heat and liquid inside the coolant system for maximum efficiency. Should be replaced each time major coolant system service is performed.

Dress up your engine bay and return functionality with a new coolant cap.
