Product Description

The Skunk2 366-05-3700 MLS Head Gasket is engineered for high-performance Honda/Acura K-series VTEC engines, supporting up to an 87.00 mm bore and featuring a thin 0.033" (~0.85 mm) gasket thickness. The robust MLS construction with HR-180 fluoroelastomer coating ensures exceptional sealing under boosted or high-rev conditions, making it suitable for performance builds.

This gasket suits modified K-series engines where maintaining head clearance and compression ratio are critical, especially in over-bore or high-output applications. Installation demands proper head surface prep, correct head bolt torque procedure and adherence to engine build specifications. It fits many vehicles equipped with K20/K24 VTEC engines - such as RSX, Civic Si, Accord, CR-V and Element - provided the engine bore and head dimensions match.

Please verify that your build uses a K-series VTEC engine, and that the cylinder bore size does not exceed 87.00 mm. Confirm that your head surface finish, bolt condition and hardware align with this gasket's performance specifications. Fitment is based on available data; ensure compatibility with your exact year, make, model and engine code before purchase.
