If you're diving into a rebuild or just looking to freshen up your BMW M54B25 or M54B30 engine, this .060" MLS (Multi-Layer Steel) cylinder head gasket is a solid choice. I’ve tackled a few projects with these engines, and trust me, the right gasket can make all the difference. This one’s designed with an 85mm bore, which fits perfectly with the specs you need for those BMW models.
First off, the multi-layer steel construction is a game changer. It’s tough and reliable, which means you can push your engine without worrying about leaks or blowouts. If you’re like me and enjoy a bit of spirited driving, having a gasket that can handle the heat is crucial. Plus, it’s built to last, so you won’t be swapping it out every couple of years.
This gasket fits a bunch of models, including the BMW 325Ci (2001-2006), 325i (2001-2005), 325xi (2001-2005), 525i (2001-2003), X5 (2001-2006), and even the Z3 (2000-2002). That’s a pretty good range, so if you own one of these beauties, you’re in luck.
To break it down a bit more, we’re talking about a thickness of .060 inches, which is ideal for maintaining compression while also providing a solid seal. It’s got the durability to withstand the demands of your engine, and it’s designed with precision to ensure a snug fit. Just make sure to double-check your bore size and other specs before you dive in.
Oh, and one more thing—this product does come with a Prop 65 warning, so keep that in mind if you’re sensitive to those kinds of things.
In short, if you need a reliable head gasket for your BMW M54 engine, this Cometic gasket is a no-brainer. It’s built to perform, and I can vouch for its quality from personal experience. Get ready to enjoy the drive again!
