HKS Stopper Type Head Gasket Toyota

Features

Point 1: Maintain high seal with high power

All three types are durable against the high engine output. Stopper structure of the bore seal is designed to be a separated type to prevent leakage even under high gas-pressure at high engine output.

Point 2: Contact surface pressure is improved!

Special coating was applied on the head and cylinder side to improve sealing performance when tightening the bolts.

With t=0.5mm gasket, NA engine's compression ratio increases compared with the stock!

The durability of the bore seal of this gasket t=0.5mm for NA engine is improved, and the compression ratio increase compared with the stock that makes this gasket ideal for one-make race. (This gasket can be installed to a supercharged engine.)

t=0.7mm for Supercharged Engine

The t=0.7mm type utilizes a stopper taller than the t=0.5mm type to provide higher bore seal durability. With a stock pistons, the compression ratio is reduced only by 0.1; it allows to maintain high heat efficiency.

t=1.0mm for HKS Capacity Upgrade Kit + Supercharger

Installing the t=1.0 type gasket to a vehicle with the supercharger enables to adjust the compression ratio of Capacity Upgrade Kit; setting range can be widened.
