does it really improve gas and power. or is it all marketing hype. i am thinking about buying one for a 2006 Jeep Grand V8 4x4. what are your opinions.
has anyone used a cold air intaker in their vehicles

It most likely won't do anything noticeable for you. Also a lot of them just make it easier to suck water up into the intake.
michaels are u serious? no right. i cant imagine an import getting that much better. the only ones imports (my knowledge is very limited) i remember that gain significant power were those older hyuandai Tiburon's since they were so horrible tuned from the factory in the first place.

Get a K&N drop in filter.
But yes, a properly designed C.A.I will increase HP and may improve gas mileage slightly.

Slap a sticker on your ride and you'll gain an instant 20 Hp gain!
Couple this with a "cold air intake" and your horsepower gains are in the 50 HP area.
Yes, all you have to do is slap a cold air intake on your car and you immediately gain 50+ HP.
Good luck. It rocks. I instantly felt the rush of my CAI. It's sweet. When it kicks in it's like a turbo. Man it really kicks in.

he's joking. CAIs are well known on the ricer circut. do they give much output? it just depends, usually the gain is 2-10 hp. they do increase the possibilities of having vaporlock (water in the intake), however the only way to have water in the intake is to drive through puddles 3 inches or more. probably more since a grand cherokee has a higher ground clearance.
Decided to go for a short RAM instead of a cold air, worried about hydrolock. Improved acceleration, gas mileage, and smoothed rough idle problem I was having. This was also on a 4 banger with a very restrictive factory air box.
Not knowing anything about your factory setup it may make a slight improvement with your V8 but nothing like putting one on a smaller car.

It will help with your HP but I cant imagine its going to help with your gas mileage at all. If you really are concerned about HP I'd open that exhaust up. From factory typically V8's exhausts are really restrictive. Slap on a catback with 2.5-3 inch piping all the way back and you will see some gains. As for gas mileage , hey its a V8 your screwed either way.
Yep, Ford Falcon/Fairmont/Fairlane manufactured from 1982 onwards come fitted with a cold air intact ducted to feed in from just behind the grill.
Even the last Carb fed 1984-1987 XF Falcons/Fairmonts had a cold air intake that fitted to the snokel on the righthand side of the air cleaner assembly and was ducted down to the grill.
Earlier Carb fed Falcons based on the blackwood body shape used from March 1979 to October 1987 show small improvements when fitted with the intake assembly from a XF Falcon, usually in the order of 5-8kw's for 6 cylinders and up to 15kw's for a Carter Thermoquad (factory carb) equipped 302 or 351 Cleveland V8 which tended to suffer from restricted power out put because of the cramped engine bay and high under bonnet (hood) temps.

Even with no turbo? You'd still get improved mileage/speed? I have a Mazda 626 LX-V6. Its a 2.5l V6, DOHC 24v.

Assume you get an extra MPG...at best with this addition. Your typical 4 banger gets around 25MPG in mixed driving. That's a 4% increase in milage. At $2.50 per gallon and driving 12,000 miles a year, that's under $50 a year in savings.
What does a typical CAI cost you? $200-$250 for a decent one that isn't a hack job.
Thta's 4-5 years it would take you to regain that investment.

Turbo, S/C, CAI, Nitrous Oxide, etc... all do the same basic thing (using different methods of course). They all add more oxygen to your car's combustion chamber in some manner. Turbos and S/Cs do this by slightly compressing air to make it more dense (IE: more O2 molecules in the same given volume). A CAI strives to do the same thing but without mechanical compression. Warm air is less dense than cold air, so if you can get cold air from the outside atmosphere (as opposed to the heated air in your engine bay) it should theoretically increase power. The power increase definitely varies from car to car, and has a lot to do with how good the origional design was. But yes, you can see noticeable HP gains if you go from feeding an engine air at say 40C vs 25C from the outside. By noticeable, I probably will be able to notice the difference when you floor it (especially if you're testing it out on a cold day). However, it's not a turbocharger... so don't get your hopes that far up.
Oh... and a well designed CAI should have a failsafe to prevent siezing your engine by sucking up water. Last time I checked that wasn't an issue (from makers like AEM and such). You need to be running a direct tube from the intake to a body of water for that... most CAI's have a simple suction activated flap that relieves any pressure if you managed to find yourself in such a situation (equivalent to driving your front end into a lake... not through some standing puddle on the road).

i have one, i generally like it. It does improve power modestly, but i don't see a gas mileage benefit. Adds nice sound too.
It does have typical aftermarket minor issues, the sealing is not perfect at the ends, i had to use additional sealing tape and it rattled against the chassis until i wrapped it in rubber.

This post right here demostrates why one should NEVER, NEVER, NEVER-EVER-EVER-EVER get car advice from ATOT.
