I am considering adding a cold air intake system to my 2001 C-5 with automatic transmission. Based on what I can read in the advertisements I should select a system brand designed for my vehicle and also upgrade the mass air flow sensor to one with a larger opening for more air intake. Need advice on the best way to proceed, verification of what I need to include for this upgrade, any brand recommendations, and any retuning that may be needed. Many thanks. Ed
I will also agree with the Vararam as a great CAI....but not sure what it would do for your vet assuming the rest of the car is stock. I know some guys will tell you it is worth it for the "seat of the pants feel" but I would be leaning toward a cat-back system first.
