Product Details

The Cometic C5111-030 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket specifically designed for the BMW S65B40 engine. This high-performance gasket features a 93mm bore diameter and a compressed thickness of 0.030 inches, providing an optimal seal between the cylinder head and engine block.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior strength and durability
  • 93mm bore diameter engineered for BMW S65B40 engines
  • 0.030" compressed thickness for precise compression ratio tuning
  • Advanced gasket technology prevents leakage and blown gaskets under high-stress conditions
  • Ideal for performance and racing applications where reliability is critical
  • Manufactured to exacting tolerances for proper sealing and longevity

Cometic MLS gaskets utilize multiple layers of stainless steel with proprietary coatings to create a gasket that is both strong and flexible. The design allows the gasket to adapt to block and head surface imperfections while maintaining a consistent seal under extreme temperatures and cylinder pressures. This gasket is an excellent choice for street performance, track use, or engine rebuilds requiring precision components.

First time customer of autoplicity. Wasn't able to use my paypal account without using Paypal credit card which I do not have, thus have set up account with autoplictiy. I guess it's a Paypal issue but would have been convenient to have used my Paypal account.

Best price online... happy customers

Went well overall. I hope these fit my truck which are larger than the generic applications that fit 25 other vehicles except my truck. Every application I have received so far are about 2/3eds the size they should be for a truck application. Hope I won't have to send these back also. At present, I would be better off removing them from a junk yard.

so far so good

I received the wrong part. I need to return and get my money refunded please. How do I go about doing this?

Very easy website to navigate

Easy to order. Now we see if the parts are right.

So far so good...

Had a little trouble adjusting the number of parts to order. Once on Amazon payment it wasn't intuitive on how to correct the quantity. I called tech services and they got me there quickly. Thanks.
