Siruda Grommet Metal Head Gasket Subaru WRX / WRX STI (GC8 / GD) / Forester (SF / SG) EJ20

Siruda Grommet Metal Head Gasket - Subaru WRX / WRX STI (GC8 / GD) / Forester (SF / SG) - EJ20

The Siruda grommet metal head gasket is a multi-layer steel (MLS) head gasket for the EJ20 Subaru WRX and WRX STI (GC8 / GD), Forester and Liberty. It is made for rebuilt and modified engines where the head seal has to hold more cylinder pressure than a factory gasket.

Choose the thickness to suit your build. It comes in a 93.5 mm bore and thicknesses of 1.1 mm, 1.3 mm or 1.6 mm. A thicker gasket lowers compression and adds piston-to-head clearance, so measure deck height and set the thickness with your engine builder. The thickness shown is Siruda's figure at the combustion seal; the body thickness is in the specifications.

Siruda's grommet design puts a metal grommet around each bore to hold back combustion gas under high cylinder pressure, including the spikes that come with knock. The grommets are molybdenum coated to limit scuffing of the head and block faces, and a nitrile rubber coating on the gasket surface helps seal the coolant and oil passages.

Note: Sold individually: this engine needs two, one for each cylinder head. Installation by a professional is recommended. Engine internals must be measured and set up by a qualified engine builder.
