Product Details

The Cometic H1631SP9063C is a high-performance copper cylinder head gasket engineered specifically for Subaru EJ25 DOHC 16-valve engines. This premium gasket features a 100mm bore diameter with a compressed thickness of .063 inches, providing precise deck height control for engine builders and performance enthusiasts.

Key Features:

  • Constructed from 99.9% pure C110 oxygen-free copper for superior sealing performance
  • Fully annealed dead soft copper material compresses easily during installation
  • 100mm bore diameter designed for Subaru EJ25 DOHC 16V engines
  • .063 inch compressed thickness allows for deck height adjustment and customization
  • Excellent thermal conductivity and corrosion resistance
  • Not susceptible to embrittlement when exposed to high temperatures
  • Ideal for engines machined for steel o-rings to handle extreme cylinder pressures

Cometic copper head gaskets are the preferred choice for high-performance and racing applications where precise deck clearance control is critical. The pure copper construction provides exceptional sealing capabilities and conforms to irregular surfaces better than composite materials. O-ringing is recommended for maximum sealing effectiveness in high-boost and high-compression applications.

Great customer service. There was a glitch in the email system, and when I called them they were very helpful and understanding. I will be doing business with them again in the future.

Great shopping experience have ordered from autoplicity several times. Only downfall is they don't offer free shipping but usually the price plus shipping is less than anywhere else.

Super easy ordering and quick shipping. This is my second time purchasing from Autoplicity.

I loved that you have low shipping cost.

I ordered a Rhino stainless steel exhaust tip for my 2009 Chev Silverado from Autopicity. It took approximately 1 week from when I placed my order until I received it. It arrived in excellant shape and was exactly as indicated. The part was very good quality and easy to install. It took me approximately 15 minutes to install, partly because I wanted to make sure of the appearance and location. I was very pleased with the service I received from Autoplicity and would definitely order again from Autoplicity.
