Cold Air Intake Question!!!!!

[kp4usa]

I installed a cold air intake (Air Raid) on my Jeep Cherokee 1995. My friend said that this modification could be damage the engine because the truck would be sucking up too much air instead of gas and will cause the truck to overheat and finally shutdown for good. Is this true? Cold air intake can damage a car? Let me know before I go back to the factory one.

It doesnt make a big enough difference. All that happens is the computer adjust for more airflow by using slightly more fuel. Only when you get into turbos and things with much more airflow do you need to worry about fuel.

lol....

The reduced restriction will improve performance/mileage (maybe not very noticable). Your computer will adjust fuel flow as needed.

If they're so bad, what are there so many on the market?

remember that you no longer getting cold air,that has to come from outside the engine compartment ,the factory air box does just this.
you are sucking in hot air and that kills perfromance. Keep in mind
the 4.0L High Output motor used in some jeeps gets its HP from
the same air box , plus it has a cam lobes that allow opening of the
valve sooner and close slower allowing more air /fuel mixture to enter
combustion chamber, this makes HP,stay with cold air box and a tuneup.

Hi guys. I think the first thing to remember here is high flow vs. cold air intake, and there is a difference. I have a 'high flow' intake on my XJ, one of these aftermarket jobs with the cone filter and the sharp looking chrome tube. I've had several conversations about benefits and downsides. Possible benefits being less intake restriction, more air down the hole, better mileage and power. Possible downsides, as stated earlier, funkie fuel mix, hot air from engine compartment, but the biggest downside (and frankly one I'm afraid of) dust getting into the intake.

Let's face it, most of these 'filters' are pretty coarse. That's how most get their 'high flow'. I live on a long dirt road, and chose to put the stock box back in for fear of sandblasting my cylinder walls.

So, let's hear it, someone lay it out here. Is a high flow intake the way to go? Are you better off to try to get cold outside air or is the hot engine air okay? Is dust going through a real concern? How 'bout a combination high flow vented to the outside...? Just curious...

Typically a cold air setup (outside of the engine compartment) will make a bigger HP gain. However, it does have a disadvantage of being exposed to dust, water, rocks, etc. It flows more because it has a thinner media, but also because it is a larger 360 degree opening, vs the factory twisty intake, which is designed to reduce noise. To answer the question about driving in dirt alot, then I would stick with the stock airbox, with a K&N drop in and removed silencers. a few HP is not worth risking your engine. Or You could also just use a short ram intake, which is inside the engine compartment, with a shield to protect it. SRI usually sees lower gains, but still has increased flow. SRI's dont really suck in too hot air because when the car is moving, air is flowing through the engine compartment. the only time it sucks very hot air is when the car is idling.
