A grommet-type head gasket that supports the tuning of a vehicle with a turbocharger.
- It improves the sealing limit by securing the surface pressure of the gasket sealing surface by employing the grommet structure.
- We also have the gasket with a thickness of t = 1.2 mm, which can lower the compression ratio for dimensional correction during overhaul and for those who use it at high boost pressure.
- Buckling may cause between the cylinder head and the sealing surface of the cylinder block due to applying increased surface pressure.
