Engine Cylinder Head Gasket Set

Product Details

Keep your ultimate driving machine running at peak performance with this premium upper engine gasket set from Elring. Known globally for their German-engineered sealing technologies, Elring is the go-to choice for enthusiast-level maintenance and professional top-end rebuilds. When executing a valve job or refreshing the cylinder head on your M54-powered E46, E39, E53, or Z3, replacing worn-out rubber and composite seals is mandatory to prevent performance-robbing leaks and maintain optimal engine efficiency.

This valve regrind set is meticulously bundled to provide an expanded selection of critical seals that goes beyond the standard factory kit. Designed as a supplementary kit, it intentionally excludes the standalone cylinder head gasket, giving builders the flexibility to pick their own head gasket thickness depending on block or head decking.
