Product Details

The Cometic C4319-051 is a premium multi-layer steel (MLS) cylinder head gasket engineered specifically for the Nissan RB26DETT engine. This high-performance gasket features an 86mm bore diameter and .051" (1.3mm) compressed thickness, making it ideal for modified and high-boost applications.

Key Features:

  • Multi-layer steel construction provides superior sealing and durability under extreme cylinder pressures
  • 86mm bore diameter accommodates stock and slightly overbored RB26DETT engines
  • .051" compressed thickness helps fine-tune compression ratios for turbocharged applications
  • Engineered with Cometic's advanced MLS technology for maximum reliability in high-performance builds
  • Viton rubber outer seal ensures optimal sealing at the coolant and oil passages
  • Stainless steel construction resists corrosion and handles extreme temperatures

Cometic gaskets are a proven choice for professional engine builders and performance enthusiasts working with Nissan's legendary RB26DETT twin-turbo inline-six engine. The MLS design allows for minor surface imperfections while maintaining excellent sealing, making it perfect for street performance and racing applications.

Awaiting Delivery

Really satisfied with my order. They had exactly what I needed for an older car and shipped fairly fast.

Found what I wanted with no problem.

The only problem was the email for the item being shipped didnt get updated fast but i did get my product so really no complaints here thank

perfect!!!

Great product, arrived promptly, and was in perfect condition.

Best price around. Great Communication. Fast shipping. What else can I ask for?<br>I have already purchased again from them.

Ordered the ARB 50QT fridge from Autoplicity b/c they had every merchant beat by more than $100. Very happy with the transaction and would highly recommend - best prices bare none. I called Auto Anything and was told they match pricing with most vendors - except Autoplicity. I can see why. My first order but not my last!

Best pricing I found anywhere on the part I needed, quick shipping, no hassle. Definitely going to be a repeat customer.

Very fast shipping, lowest prices on the web.
