Product Details

The Cometic C5693-066 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket specifically engineered for Buick Stage I and Stage II V6 engines. This precision gasket features a 4.090-inch bore diameter and .066-inch compressed thickness, making it ideal for performance builds requiring enhanced sealing capabilities.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • 4.090-inch bore diameter optimized for Buick Stage I/II V6 applications
  • .066-inch compressed thickness provides excellent combustion sealing
  • High-temperature resistance withstands extreme performance conditions
  • Engineered to handle increased cylinder pressures in modified engines
  • Precise manufacturing ensures optimal fitment and reliability

Cometic's MLS head gaskets utilize multiple layers of stainless steel with advanced coating technology to provide maximum sealing under the demanding conditions of performance and racing applications. The layered design allows the gasket to adapt to minor surface imperfections while maintaining consistent clamping pressure across the entire sealing surface.

Very fast transaction and shipping info.. Best price found on the internet..

Excellent place to deal with. I am a returning customer and love the fast shipping!!

Auotplicity had the lowest prices and S&H online. I will shop here again. Thanks Derek!

After shopping around for a specific cargo carrier, Autoplicity had the best total price by over $50 and great ratings, so I gave them a try. I received the SportRack Aero XL - A90275 last Thursday and am VERY impressed with their price and service. The cargo carrier arrived quickly (ordered Sat, rec'd Thurs) and in fine shape. I will recommend Autoplicity to my friends, and plan to shop with them for my future automotive needs.

Prices are very good. There was a slight issue with my order, but it was taken care of after being passed around to a few different departments when I called. Would order from them again.

So far so good! Just ordered the parts I needed for my car which I've been trying to find EVERYWHERE without success, until I arrived at autoplicity. Great price, and with a lifetime warranty I'm assuming great quality. I have faith that when the product arrives I will be highly satisfied.

Great price on my short ram air intake... Actually, best I could find on the Internet. Product shipped the day after the order. Haven't had any problems so far, but it was only shipped just today.

I like that I could use my Amazon account.

Great price, fast shipping, excellent customer service. I will definitely do business with them in the future.
