I plan on installing an aftermarket airbox. I like the construction of it, and how the brackets are already there for you. Very easy installation. I was wondering if you guys have heard of this company and have had any experience with them? I also have heard of insane performance. I need help trying to choose between them two. Thanks for your help and heres the links and pic for cfmracing.....

CFM is a great company to deal with. Awesome products at a good price.
