What you wanna know?
I have a few articles that I saved.
Also from what Ive recently found out the bullit intake is not worth it anymore due to certain companys making better intakes now that are better then the bullit for the same price itd cost you to do a bullit swap.
Actually aftermarket intakes go for less than an unported bullitt intake with the install kit to put it on with they go for about 1600 or more, you can get an aftermarket for around 1100~ complete, and it actually ADDS horsepower with no porting needed to it. A larger tbody and ported stock or aftermarket upper intake plenum will net you MORE gain than an expensive bullitt intake swap.
