If you're diving into some serious engine work on your BMW M54B25 or M54B30, you’re going to want to check out this .080" MLS Cylinder Head Gasket. It’s made from multi-layer steel, which means it’s built to handle the heat and pressure you throw at it. I’ve used this gasket on my own projects, and it really stands up to the demands of performance driving.
Now, let’s talk specifics. This gasket has an 85mm bore, which is perfect for those of us looking to maintain that factory fit while still pushing the limits. Whether you're rebuilding your engine or just replacing a worn-out gasket, this one’s got you covered. It fits a range of models, including the 325Ci from 2001 to 2006, the 325i from 2001 to 2005, and even the X5 and Z3. So, if you’ve got one of these beauties in your garage, this gasket is a solid choice.
Just a heads up, it’s compliant with Prop 65 regulations, so you can feel good about using it in your ride. I appreciate that Cometic has put thought into the materials and regulations, which shows they care about quality and safety.
