TRD 4AGE 16v 0.8mm Metal Head Gasket for AE86 Toyota Corolla GTS

This is a genuine TRD 0.8mm Head Gasket from a Japanese Toyota Dealer.

 Usual OEM gasket has a height of 1.2mm – this metal gasket will be just under 0.8mm when compressed.  This small difference in compressed height will result in a half point increase in compression ratio (0.5).  If you are on a stock ECU this will give you a slight increase in torque and power at all RPM’s. With a standalone, the gains can be even greater.
