Choosing a Cold Air Induction

Our intake is designed to maximize performance with your car's stock calibration or with a tune. With the stock calibration, you can expect about a 25 HP gain along with awesome sound from the supercharger. You can really hear it sing as RPMs increase. It gets addicting!
With a tune and/or other power additives, you benefit from our large filter size and air box area which allows air to enter from the stock inlet duct without restriction.
Whether the intake is your only mod or first on a list of anticipated mods, the Roto-fab intake has proven to be a great choice for the ZL1. Be sure to check out our Big Gulp as well as other ZL1 engine bay accessories.We have several reputable dealers right here on this forum that have extensive knowledge of our products and can offer you great service.

Another advantage to the Rotofab unit is it looks like GM put it there. The regular black one I'm talking about of course. It looks like a cleaner version of the Z28 intake imho. Needless to say this will be my first modification lol.

Can't lose with either Rotofab or CAI but I like the look of the CAI.
