RacingLine Coolant Expansion Cap

This RacingLine coolant expansion tank cap is a billet replacement for the factory plastic cap on a wide range of Volkswagen Group performance models, from the Golf R and GTI to the Audi S3, RS3 and TT, Cupra Leon and Skoda Octavia. It has sophisticated internal springing and bleed off, which RacingLine says keeps the expansion tank at its correct pressure and ensures that pressure is never exceeded. The brand points out that worn stock caps lose the ability to hold pressure, which reduces cooling efficiency. It is a full replacement for the original cap, not a cover that sticks on over the plastic one.
