Scope of delivery: 2 × special cylinder head gaskets for Audi RS4 B5

These gaskets allow you to adjust the compression ratio for planned cylinder-head work or performance upgrades. This can permit significantly higher boost pressures and therefore higher power outputs. With standard compression ratios, the original pistons may not withstand the resulting temperatures or may operate close to the knock limit.

Made in Germany
