If you're diving into a BMW S14B20 or S14B23 build, you know the importance of a solid foundation. This Cometic Cylinder Head Gasket is a game-changer, specifically designed for those of us who want to push our M3s to the next level. With a thickness of just 0.040 inches and a bore size of 93.4mm, it’s built to handle the pressures of performance without compromising on reliability.
What I really appreciate about this gasket is its multi-layer steel construction. It’s tough as nails, which means you can trust it to seal properly even under high-stress conditions. You won't have to worry about leaks or blown gaskets when you're out tearing up the track or cruising down the highway. Plus, it fits perfectly in the BMW M3 models from 1988 to 1991, so you know it’s made for your ride.
Now, I should mention the Prop 65 warning—yeah, it’s there. But honestly, most performance parts come with a bit of a disclaimer these days. Just keep that in mind if you're sensitive about these things.
In short, if you’re looking to boost your engine's performance and ensure a tight seal, this gasket is worth considering. It's not just another part; it's a crucial piece of the puzzle that can make a real difference in how your engine performs. Trust me, you’ll feel the difference when you hit the gas.
