Product Details

The Cometic C4321-030 is a high-performance multi-layer steel (MLS) cylinder head gasket engineered specifically for the Nissan RB26DETT engine. This precision-manufactured gasket features an 88mm bore diameter and .030" (0.76mm) compressed thickness, making it ideal for performance builds and engine rebuilds requiring reliable sealing under high combustion pressures.

Key Features:

  • Multi-layer steel construction for superior strength and durability
  • 88mm bore diameter designed for Nissan RB26DETT applications
  • .030" compressed thickness for optimal compression ratios
  • Advanced sealing technology prevents combustion gas leakage
  • Resistant to extreme temperatures and pressures
  • Precision-cut embossments ensure even clamping load distribution

Cometic MLS gaskets utilize multiple layers of stainless steel with specialized coatings to accommodate engine movement and thermal expansion while maintaining a positive seal. The .030" thickness option allows engine builders to fine-tune compression ratios for their specific performance goals, whether for street, drag racing, or road racing applications on the legendary RB26DETT twin-turbo inline-six engine found in Nissan Skyline GT-R models.

Very easy to order and checkout.

Prices were good and the order shipped promptly. The email notice of shipment was a little late. It came after the order had arrived.

I was so happy to find the chrome GMC license plate that my boyfriend has been looking for on this website at a very affordable price! It was easy to find and easy to order. Can't wait to get it in the mail!

Product delivered as expected within 4 days. Lowest price on the web. No complaints.

This was an easy transaction, keep me notified thoughout the entire shipment. Price is what got my attention in the first place. I will be back for future needs.

Nobody else had part in stock. Instant shipping and a good price. Will do business again!
