HKS Stopper Head Gasket for Mitsubishi Evolution X 4B11T - 1mm (87.5mm Bore / 9.1 CR)

$280.00

$280.00

Engineered for the high-cylinder pressures of forced induction, the HKS Stopper Head Gasket is a critical upgrade for the Mitsubishi Evolution X (4B11T). This multi-layer steel (MLS) gasket utilizes a "stopper" type design, featuring a folded-over layer around the combustion chamber to provide a high-pressure seal that prevents combustion leakage where standard gaskets often fail.

This gasket is specifically designed for engines with an 87.5mm bore and maintains a 9.1 compression ratio, making it an ideal choice for performance builds requiring precise tolerances and improved thermal conductivity across the deck surface.
