The Racingline Performance Billet Coolant Cap is beautifully over-engineered in customary Racingline Performance fashion to give an exquisite feel and exceptional product experience. The Racingline Performance Billet Engine Coolant Cap provides a complete replacement for the plastic OEM version.

The coolant cap is a critical part of your vehicle's cooling system to ensure that correct pressure is maintained and never exceeded. 
Older worn stock coolant caps can sometimes lose the ability to hold the correct pressure keeping your cooling system at maximum efficiency. 
This is an engineered, billet replacement coolant cap, designed to replace the cheap plastic original, with a sophisticated internal spring bleed off mechanism. 

Not to be confused with cheaper 'covers' which simply stick over the top of your original cap.
