RacingLine's replacement Billet Coolant Expansion Cap for MQB & A5-platform models is a full replacement for the original plastic cap. Keeping that coolant expansion tank sealed is a critical part of your car's cooling system. RacingLine's replacement cap will ensure that proper pressure is maintained, and never exceeded, especially on high-performance engines.
