What kinds of Gains are you looking for by installing a CAI.......Better Fuel Mileage and/or More H.P. and do you have any other Performance Mods on your Suburban Now??I am sure this has been covered before, but I cannot find it. I have a 1999 Suburban with the 5.7 liter in it and I am looking for a good cold air intake. What are the pros and cons of the different ones and is it worth the money?
