purpose of upgrading air intake
I have never been much of a gear head but what kind of performance do you get with a cold air intake? I am looking at possibly getting a volant cold air intake system. Thanks:great:Semper FI

The Performance Gains by installing a CAI......just by itself are Small.....to receive Better Gains in Performance......along with installing a CAI, would be installing a set of Long Tube Headers and Cat Back Exhaust....
These 3 Bolt-ons.....will give you Solid Gains Re-guarding H.P. and M.P.G......Adding a Tune....Either Hand-Held or Custom Tune.....gives you your Best Bang for your $$$$.

The actual Purpose of a CAI is to lower the intake air temp on your air charge entering your engine. Cooler air is more dense, so you get more into the engine, effectively increasing your dynamic compression ratio. This is why forced induction engines will use intercoolers to drop the temp, so they can get more air pushed in.
As was stated though, the effect is generally minimal from a CAI with no other mods.1986 Chevy G20 Tow Rig - 5.7 TBI conversion

The CAI intakes also give better throttle response.

They do help, and every truck and every system will react different, but right off the bat you will most likely feel a difference in your upper rpm range as they will be able to climb a little quicker and have better HWY passing ability. At least thats what I have always noticed the most. If you do an exhaust I would recommend just going to a reputable exhaust shop, paying a grand for an aftermarket cat-back isnt worth the extra money over the gains a good shop will give you. Also, big name brand isnt always the best. I had a magnaflow on my suburban and was not happy with it, the muffler had horrible HWY drone and it only lasted 2 years and had rotted through, I replaced it with a Flo-Pro muffler and have been happier. Better performance gain, no drone and way better sound on my Beast!99 K1500 Suburban LT "THE BEAST"

As said above the colder air will wake up the motor better but getting it in faster you should get it out fast too. Also between a chrome tube and a black tube. You might like the looks of a chrome tube but you will get a better performance from the black tube.08 Z71 Avalanche Mods to date: K&N CAI,Hellwig Swaybars and End Links, Corsa Sport Exhaust, Superchips Programer,IPCW LOF & 3rd brake light and tails, AMI Gas door,Show Hooks and Door locks, Enkei Wheels, with Pirelli tires, StreetScene Bowties, Grant Steering wheel,Muth signal mirrors,SSBC Big Brake kit,Huskyliner Mug gards,Floor mats and Hood shield, McGard Lug nuts and locks, Bedrug, Cervini's Ram Air hood,35watt HID Fog lights, Sylvania bulbs all around ZXE's Highs and Lows, WhiteNight Back up lights,Sirius and HD Radio, SnugTop sitting on deck now Got a Softopper on now,Tempress Boat Hatches....
