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.

I had initially received my kit with a missing o-ring resulting in a leak, but that was resolved very quickly thanks to RacerX's fantastic customer service. Anyways, this kit is pieced together quite beautifully with ridiculously nice components and the install process was very simple. I would normally see oil temps hover around 210-220°F with simple highway driving, but with this kit installed, it stays almost exactly at 185°F. It peaked at 199°F during an autocross event on a relatively long and fast course where I was on the rev limiter for seconds at a time. Really don't have any complaints besides the tight fit between the airbox and oil cap. Awesome product!
