Tuning the FA20 engine with a supercharger is becoming more and more popular, and more people are stepping up. At that time, many people face the problem of gasket leakage.
This gasket is an even stronger type than the conventional stopper type for supercharger tuning.

*The above compression ratio is a design calculation value.

■ Features

POINT-1
The surface pressure of the gas seal surface has been reliably secured, increasing the sealing limit.
POINT-2
By using it in combination with a reinforced head bolt, a higher sealing effect can be obtained.
POINT-3
By adding this to the stopper type currently on sale, the thickness variations have increased and the range of compression ratio settings has been expanded.
Notes

Due to the high surface pressure, some buckling may occur on the sealing surface between the head and cylinder.
