If you’re diving into the world of Mitsubishi engines, you’ve probably heard about the 4G63 and 4G63T. This 0.027" MLS Cylinder Head Gasket is a solid choice for anyone looking to boost performance without breaking the bank. With an 87mm bore, it’s designed for those who want to push their engine to the limit while keeping things reliable.
What I really appreciate about this gasket is its multi-layer steel construction. It’s not just for show; this material is tough and can handle the heat and pressure that comes with high-performance setups. If you’ve ever had a head gasket fail on you, you know how critical it is to have something that can stand up to the rigors of spirited driving or track days. Plus, it fits a range of models, including the Mitsubishi Eclipse from '90 to '92 and '95 to '99, as well as the '89 to '92 Mitsubishi Galant. So, if you’re working on one of those, you’re in luck.
One thing to keep in mind is that this gasket isn’t for the 1996-2005 Lancer Evolution. So, if that’s your ride, you’ll need to look elsewhere. But for those of us rocking the earlier models, this gasket is a fantastic upgrade. It’s got that perfect balance of durability and performance, making it a go-to for anyone serious about their Mitsubishi build.
Just a heads up, if you're in California, it’s worth noting that this product comes with a Prop 65 warning. But don’t let that scare you off; it’s just a standard precaution. Overall, if you’re looking to keep your engine sealed tight and running strong, this Cometic gasket is definitely worth considering.
