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

Fits perfectly and looks awesome under the hood. I think I’m losing less coolant too. Lol.
