High-Performance Sealing with HKS Grommet Type Head Gasket
When head bolts are tightened, the cylinder block and head—both non-rigid components—can create uneven gaps and surface pressure across the gasket interface. These conditions are further impacted by the high combustion pressures and vibrations encountered during engine operation. A high-quality head gasket must not only distribute sealing pressure as evenly as possible but also adapt dynamically to maintain a reliable seal under constantly changing conditions.
Grommet Type Head Gasket for FA20 Engines
Turbocharging and supercharging the FA20 engine has become increasingly popular. However, these high-performance upgrades often lead to head gasket failures due to the added stress. To combat this, HKS has developed a new grommet-type head gasket that surpasses traditional stopper-type designs, offering superior sealing for forced-induction applications.
Features and Benefits
Enhanced sealing performance through a grommet structure that ensures consistent surface pressure across the gasket.
Available in 1.2 mm thickness to help lower the compression ratio, ideal for high-boost setups or dimensional adjustments during engine overhauls.
Minimizes the risk of buckling between the cylinder head and block sealing surface under increased pressure.
