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.

We’re proud of the over-engineering that we’re put into this cap. Manufactured from CNC 5-axis machined billet 6061 aluminium and hard anodised in gloss black for a long lasting, high quality finish. An internal springing mechanism provides the click – and ensures absolute tightness when fitted, even with the heat soak from a high performance engine. A laser etched ‘Racingline’ is the finishing touch and seal of approval for this lovely upgrade.
