Mugen Metal Head Gasket RSX 02-06, Civic Si 01-05

Description

A two-layer construction is used instead of the normal three-layer gasket plate construction, and a rib (+0.07mm) is laser-welded close to the plate surface sleeve to prevent blowout occurring at high compression. This Mugen head gasket raises the compression ratio by 0.4 points. Construction is entirely of stainless steel.
