Honda B21A1 .045" MLS Cylinder Head Gasket - Your Engine's Best Friend

If you're diving into a rebuild or just looking to fix up your 2.1L Honda Prelude from 1990-1991, this Cometic Cylinder Head Gasket is a solid choice. It’s made from multi-layer steel, which means it's tough and built to last. The .045-inch thickness is just right for maintaining proper compression while ensuring a good seal. Trust me, you want that peace of mind when you're pushing your engine.

What Makes This Gasket Stand Out?

  • Material: Multi-layer steel construction gives you durability and resistance to blowouts.
  • Bore Size: Designed for an 84mm bore, it fits snugly on your B21A1, so you won't have to worry about leaks.
  • California Proposition 65: Yes, it complies, so you can feel good about your purchase.

Why You Need This Gasket

Let’s face it, a good head gasket is crucial for making sure your engine runs smoothly. If you’re dealing with an old Prelude, you know how vital it is to have reliable parts. This gasket helps maintain that perfect seal under pressure, which means better performance and longevity for your engine. Plus, it’s designed specifically for the B21A1, so you’re not just throwing a generic part in there. It fits like a glove.

Fitment

Perfectly suited for the 1990-1991 Honda Prelude with the B21A1 engine. No guesswork here—this gasket is made for your ride. Just a heads up, if you're planning to run this with any modifications, be mindful of your compression ratios.

Final Thoughts

In the end, if you want to keep your Prelude running like it should, this Cometic gasket is a no-brainer. It’s a simple piece, but it plays a huge role in your engine’s health. Grab one, and get back to enjoying the drive!
