Racingline Billet Expansion Tank Cap

The Racingline Performance Milled Aluminum Coolant Expansion Tank Cap is highly engineered in the Racingline Performance style to provide a quality feel. The Racingline Performance Milled Aluminum Coolant Expansion Tank Cap completely replaces the plastic OEM version.

We are proud of the engineering excellence that has gone into this cap. Manufactured from CNC 5-axis milled 6061 aluminum and anodized in gloss black for a durable, high-quality finish. An internal spring mechanism provides the click and guarantees absolute tightness when installed, even under high heat from a high-performance engine. The laser-etched "Racingline" is the finishing touch and stamp of approval for this beautiful upgrade.

Installation is pretty straightforward – but you will need to carefully remove the rubber seal from the factory oil cap and install it on the new RacingLine oil cap before using it for the first time. Then enjoy that 'click' again and again.
