If you're diving into the world of BMW tuning, you know that the little details can make a huge difference in performance. That’s where the BMW S14B20/S14B23 .140" MLS Cylinder Head Gasket comes into play. This isn’t just any gasket; it's crafted from multi-layer steel, which means it’s built to withstand the heat and pressure that come with pushing your engine to its limits. With a bore size of 94.5mm, it fits snugly for those who want to keep their M3 running like a dream.
Now, I’ve used my fair share of gaskets over the years, and I can tell you that the quality of the material really matters. This gasket has a robust construction that gives you confidence, especially when you’re tuning for more power. It’s designed to handle the rigors of both street and track use, so you can push your BMW without worrying about leaks or failures.
Just a heads-up, if you’re in California, you’ll want to be aware of the Prop 65 label. It’s always good to know what you’re dealing with, and yes, this one does have that label attached. But don’t let that scare you off; it’s all part of keeping things transparent in the automotive world.
For those of you who own a BMW M3 from 1988 to 1991, this gasket is a perfect fit. It slots right in for the S14B20 and S14B23 engines, so you can rest easy knowing you’re using a part that’s been engineered specifically for your ride. Whether you’re a weekend warrior or a daily driver, this gasket is a solid choice to keep your engine sealed tight and performing at its best.
