Product Details

The Cometic C4237-066 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for Honda B Series hybrid VTEC engine builds. This gasket enables the popular combination of a VTEC cylinder head with a non-VTEC block, making it essential for performance enthusiasts building hybrid B-series engines.

Key Specifications:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • 81mm bore diameter—optimized for stock and mild overbore applications
  • .066 inch (1.68mm) compressed thickness for precise compression ratio tuning
  • Engineered for VTEC head to non-VTEC block hybrid configurations
  • Accommodates the different coolant passage layouts between VTEC and non-VTEC blocks

Performance Benefits:

  • MLS technology provides exceptional resistance to combustion pressure and extreme temperatures
  • Allows builders to dial in compression ratio for boost or high-RPM naturally aspirated applications
  • Eliminates head gasket failure common with OEM gaskets in performance builds
  • Compatible with both turbocharged and naturally aspirated setups

Cometic MLS head gaskets feature multiple layers of stainless steel with an elastomeric coating that recovers with thermal cycling, maintaining consistent sealing under demanding conditions. This gasket is a must-have component for anyone building a Honda B Series VTEC hybrid engine for street performance, road racing, or forced induction applications.

Excellent shipping received very fast and well packaged

My dealings with this site have been great. I made a mistake on my address and emailed them to change it. I got quick responses every time. Would definitely use the site again.

My second time ordering from Autoplicity. I price shop online and Autoplicity had the lowest price both times. Fast ship with email notifications. Autoplicity will now be my "First" site I go to for my auto accessories. Great job Autoplicity.

Autoplicity was very fast and easy to oredr from. prices are great and looking forward to placing future orders.

Had a problem but they fixed it. Fast shipping.

Quick shipping and great price!

So far I am happy with Autoplicity's order status updates. I like when shipments are in process and with the updates I know progress is happening. When an order doesn't seem to be moving along a customer wonders what the hold up is. Well so far I don't have to wonder which makes me more patient in waiting for my order. Thank you, I will explore Autoplicity's website for more cool stuff for my car.
