Product Details

The Cometic C5691-045 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Buick Stage I and Stage II V6 engines. This precision gasket features a 3.860-inch bore diameter and a compressed thickness of .045 inches, providing excellent sealing performance for both stock and modified applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • 3.860-inch bore diameter optimized for Buick V6 applications
  • .045-inch compressed thickness for precise compression control
  • Designed for Buick Stage I and Stage II V6 engines
  • Accommodates thermal expansion and cylinder head movement
  • Superior recovery characteristics compared to traditional composite gaskets

Cometic's MLS gaskets feature multiple layers of stainless steel with advanced coating technology, providing exceptional resistance to compression fatigue and combustion seal deterioration. The gasket's design allows it to maintain consistent clamping pressure across the sealing surface, even under extreme cylinder pressures found in performance and racing applications.

Highly recommend ordering from this company. I was in deep search for a product that everybody else told me I wouldn't find until next year (e.g. 4 wheel parts). Autoplicity knew someone that had the product and made the transaction as seamless as possible. I know where to look for future orders. <br><br>One very happy customer!

The order was placed on a weekend (Order #30758 <br>Order Date: Saturday, September 15, 2012 Order Total: $31.73 <br>It was processed on the first business day. I couldn't ask for a quicker response.<br><br>Good joob all !!!<br>Marty Spellman
