Product Details

The Cometic C4238-066 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Honda B18A1 and B18B1 engines. This precision-manufactured gasket features an 81mm bore diameter and .066" (1.68mm) compressed thickness, providing exceptional sealing capability for stock and modified applications.

Key Features:

  • Multi-Layer Steel construction for superior durability and heat resistance
  • 81mm bore diameter designed for B18A1/B18B1 engine blocks
  • .066" compressed thickness for precise compression ratio control
  • Advanced MLS technology provides maximum sealing under extreme cylinder pressures
  • Embossed stainless steel layers with elastomeric coating for optimal conformability
  • Reusable design allows for multiple installations when properly maintained

Cometic MLS head gaskets are a proven choice for enthusiasts building reliable Honda powerplants. The multi-layer design distributes stress more evenly than traditional composite gaskets, making this gasket ideal for turbocharged, supercharged, or high-compression naturally aspirated builds. Compatible with both aluminum and cast iron cylinder heads when surfaces are properly prepared to RA 50-60 microfinish specification.

First of all, I can not believe how fast I recieved my order, 2 DAYS! Best of all, the instructions made it easy for a non mechanic like me to install.

Best price I could find on the web even after paying for shipping! Shipped in a couple of days and great service!

The ordering process was very simple and the prices could not be beat. The processing time to ship the order was a little longer than usual, but for the price savings, it was well worth it!

Great customer service, item shipped quickly. Very satisfied.

Good prices and fast checkout.

Easy to order!

I couldn't find these ARP studs anywhere else for this price! $20 less than ANYWHERE! Definitely coming back to shop at Autoplicity.
