If you're diving into the world of BMW engines, specifically the M42B18 or M44B19, you’ll want to check out this Cometic .140" MLS Cylinder Head Gasket. This isn’t just any gasket; it’s built from multi-layer steel, which means it’s tough enough to handle the demands of your spirited driving and engine performance upgrades.
Now, let’s talk specifics. This gasket has an 86mm bore, making it a solid choice for those looking to maintain or boost their engine’s integrity. Whether you're rebuilding your engine or just doing some routine maintenance, this gasket is designed to fit snugly without any issues. It’s compatible with several models, including the BMW 318i (1991-1999), 318is (1991-1999), 318ti (1995-1999), and the Z3 (1996-1998). Just make sure you’re working with the right engine setup.
One thing to keep in mind is that the .140" thickness can affect your overall compression ratio, so if you’re planning on pushing your engine's performance, you might want to consider how this fits into your overall build. It’s a straightforward install, but if you’re not familiar with gasket replacements, it might be worth getting a hand from someone who knows their way around a BMW engine.
And hey, just a heads up—this product does have a Prop 65 warning, so make sure you’re aware of that if you’re in California. But if you’re looking for a reliable gasket that can hold up under pressure, this one’s worth considering. It’s solid, dependable, and ready to keep your engine running smoothly.
