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 head gasket raises the compression ratio by 0.4 points. Construction is entirely of stainless steel.

Engine applications: K20A Type-R (DC5/EP3), K20A2, K20Z1, K20A3
(Fitment is for PRB style K-series head)
