Product Details

The Cometic C4394-075 is a Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for BMW M20B25 and M20B27 inline-6 engines. This precision-manufactured gasket features an 85mm bore diameter and 0.075-inch compressed thickness, providing reliable sealing for stock and modified applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • 0.075-inch (1.91mm) compressed thickness for proper compression ratio
  • 85mm bore diameter designed for M20B25 and M20B27 engine blocks
  • Engineered to handle thermal expansion and contraction cycles
  • Eliminates gasket failure and coolant leaks common with stock gaskets
  • Suitable for street, performance, and mild boost applications

Cometic's MLS gaskets utilize multiple layers of stainless steel with proprietary coatings to create a superior seal that withstands extreme cylinder pressures and temperatures. This gasket is ideal for BMW E30, E28, and E34 chassis equipped with 2.5L or 2.7L M20 engines seeking a reliable OEM replacement or upgrade for performance builds.

Great customer service

Site use was easy, and product shipped promptly after ordering. Price was the best I could find, would use this business again.

Lowest price on EBC brakes for my Subaru. Good speed on processing.

good

First I found Autoplicity through The Find, they already had the item discounted, other than all the other online stores where you needed to search for coupon codes. Then the transaction was very simple, they accepted PayPal which was the payment method I wanted to use.<br>I'm very happy with my purchase and the service I got from Autoplicity.

Quick easy ordering Best price of all internet and local search

Ordered a CAI kit and Autoplicity had the lowest price. They're website didn't correctly match my vehicle to the product and it took a few days to ship. They're support was friendly and quick when I emailed them about the delay.
