Cold Air Intake

I am considering installing cold air intake on my 2007 Honda Civic LX for my first mod. I am planning to order the K&N cold air intake kit that I saw on 4wheelonline. Is it a proven way to improve a vehicle's fuel consumption and horsepower?

Only if you're driving MUCH FASTER than the speed limits:

COLD air = power @ high engine rpm's.

WARM air = economy @ low/mod. engine rpm's.

I wouldn't fork out the money for those!! I got a cold air intake for my s10 on eBay for $35 and personally wouldn't spend more than that because it's not worth it!! I got a solid 3mpg improvement on my s10 with the 4.3l so it worked for me!!

If you want to know how that specific intake does on your car, I would check a Civic forum. I wouldn't consider anything less than meticulous mileage records or a before and after dyno reading to be proven, though. Most newer car's have pretty good intakes from the factory, so you're not likely to see any improvement (unless you're doing other mods that need more air). A clean or better flowing air filter won't give you better MPGs, see the last point on this page Gas Mileage Tips - Keeping Your Vehicle in Shape

Waste of money and it will reduce fuel economy, but not by any noticeable amount.

If you want more speed, reduce the weight of the vehicle.

If you want more MPG, change your driving behavior.

I find it pointless to own a "fast" car. You'd have to spend tens of thousands of dollars to match the speed and excitement of riding a $2,000 sportbike.

I'd also like to add to this that mountainous areas(those with hills that are 30% slope or better for more than 3-4 blocks) get cold air intake to improve mpg, and flatter areas get the warmer intake for mpg!!

The way they work is only if you believe they work and want them to work. Basically they tie into your aura and somehow help combustion. So you have to keep records, because you want it to work you change your habits. Changing habits actually does work. Therefore the intake does improve economy.

Pop your hood and look at the factory intake. There's probably a duct going from the grille to the air box. A CAI, one might say.

Did you ever happen to test a warm-air intake on your 4.3L S10?

I did, but like I said I live in a mountainous region and the lack of power caused it to loose mpg will the cold air increased my mpg due to not having to downshift from fifth anymore!!
