Thing of beauty. It mounts to both top beam and the bottom inner shelf. Much more solid than other brands, for me any ways. And it keeps the oil were it should be.
But I will mention that my CAI, the Skunk II, is not the best fit. It rubs against the air box. It's a big airbag.
I also have the rear LCA, 5 stars for that also. These parts are just so well made. Buy one you'll see.
