If you’re diving into a rebuild or just looking to refresh your BMW's engine, the Cometic Gasket M20B25/M20B27 cylinder head gasket is a solid choice. This isn’t just any gasket; it’s crafted from multi-layer steel, which means it’s tough enough to handle the heat and pressure of your M20 engine. With a .070" thickness and an 85mm bore, it’s designed to give you a reliable seal that can withstand the demands of spirited driving.
Now, let’s talk fitment. This gasket is compatible with a range of models including the 325e from '84 to '87, the 325i from '87 to '93, and the 325is from '87 to '91, among others. If you’ve got a BMW 528e from '82 to '88, you’re in luck too. Just make sure your engine is one of the M20 variants, and you’ll be good to go.
One thing to keep in mind: if you’re planning on pushing your engine hard, this gasket can handle it. It’s built for performance, so whether you’re hitting the track or just enjoying a spirited drive on your favorite backroads, you can trust it to keep everything sealed tight. Just a heads up, some users have mentioned needing to do a bit of trimming for optimal fitment, but that’s pretty common with aftermarket parts.
Overall, if you want a gasket that won’t let you down and can take the heat, this Cometic option is worth considering. It’s straightforward, reliable, and gets the job done without any fuss.
