 Product Description


This cap not only keeps coolant in your engine where it should be but also maintains the higher
pressure required in your vehicles cooling system.  This cap wears out over time due to exposure
to high temperatures under the hood and can become ineffective in maintaining pressure.

This clean looking blue cap is a great part for any VW/Audi engine bay.
