Product Description

Introducing the Grommet-Type Head Gasket, meticulously crafted to support and optimize vehicle tuning, especially in turbocharged applications. Engineered with precision and expertise, this specialized head gasket boasts a grommet-type design, tailored to accommodate the demands of turbocharged engines. Designed to endure the intensified conditions brought on by turbocharger tuning, this gasket ensures a reliable seal, effectively containing combustion pressures within the engine cylinders. This contributes to enhanced engine performance and durability, vital for vehicles undergoing tuning adjustments, especially with added turbocharging. Trust in the reliability and precision engineering of the Grommet-Type Head Gasket—an essential component in optimizing your vehicle's performance, specifically in turbocharged setups.

  • By using the grommet structure to secure the surface pressure of the gasket sealing surface, increases the sealing limit.
  • Additionally, for those who utilize it at high boost pressure or to compensate for displacement during overhaul, we offer a gasket with a thickness of t = 1.2 mm, which can lower the compression ratio.
  • Applying more surface pressure can result in buckling between the sealing surface of the cylinder block and the cylinder head.
