Easy to install, make sure you remove the old o rings....mine were stuck on the manifold..I used a small pick to dig them out...also these little rings are super easy to loose, might be worth it to buy two packs..

Perfect fit, great quality, and a great price for peace of mind.

good stuff fast shipping love it

As good as OEM. I find that I usually have to work them a little with my fingers and stretch them out just a hair for perfect fitment. These are my go to when replacing the balance tube o rings! A must if you're doing a plenum pull.
