Product Description

The Skunk2 366-05-4200 MLS Head Gasket is engineered for high-performance Honda/Acura K-series VTEC engines (K20 and K24). With its robust multiple-layer steel construction, laser welding, and HR-180 fluoroelastomer sealing layer, this gasket offers outstanding durability, reliability and sealing capability under severe conditions such as high RPM, boosted or high-output naturally aspirated builds.

It supports a maximum bore of 88.00 mm (3.464") and up to 1.1 mm overbore, making it suitable for serious engine builds requiring larger bore cylinders while maintaining proper head seal. The 0.043" (1.1 mm) thickness helps manage compression ratio and head clearance in modified engines.

This gasket fits a variety of Honda/Acura vehicles equipped with K20 or K24 VTEC engines - including the RSX, TSX, Accord, Civic Si, CR-V and Element models listed above. Before installation, ensure your block and head surfaces are properly prepped, verify bore size and head bolt hardware is correct. Fitment is confirmed through the listed years; coverage beyond 2011 or other engine families is unconfirmed at time of listing.
