BWAHAHAHAHAHAHAHAHAHAHAHAAAAAAAA....*gasp*.....BWAHAHAHAHAHAHAHAHAHAHAHAAAAAAAA

umm...it actually helps out at higher RPM's and the response is a hell of a lot better. And I'm sure "BWAHAHAHAHAHAHAHAHAAAAAAAAA" doesnt answer my question. Thanks.

Yeah, it does. It will add nothing but noise to your 100hp four banger. Mark my words.

chrysler makes 100hp four bangers? jebus.

Yeah, th 2.4 i4 produces a LOL-worthy 140hp.


I got a 2.5L V-6. And are you thinking of exhaust when you say it will produce "nothing but noise"?

No, intake noise will increase. FROM UNDER TEH HOODZ!


My friend put one in and the intake noise sounds great if anything. His exhaust though, is ridiculous. I know that a cold air intake won't make my car into a ricer, but they do help somewhat in some areas and for that cheap a price, why the hell not.

most cars in my experience get largest increase at midend, some at top end, and none (or slight loss) at low end

on my previous car, there was good gains all around. the sound was enough justification, though.

on some cars with k20 honda motors, gains are quite large

trust me itll make sound. the kind of sound an intake on a 4-cylinder car will make

:puts on flamesuit:


I already put in a good sound system with 2 12" subs, so no worries there.

that cold air intake probably won't even offset the loss you got from the added weight from those subs

just fyi

Also, just to clarify, I'm not talking about Short Ram Intakes which suck in hot air and are extremely noisy, Im talking about Cold Air Intakes, which suck in, duh, cold air and aren't near as noisy. Theres quite a difference.

i have an intake, it depends on the car but, mine gave me power. Nothing incredible, but it is measurable.

on some cars you can just strap a cone filter where the filter box is, but that just gives you a short intake, which generally is worse than a cold one.

Eh, I just hope you realize that they just help you isolate the air filter from the rest of the engine compartment to help reduce the temperature increase from the ambient heat given off by the engine. Some are simplistic and literally are no more than a "heat shield." Some place your air filter in a different spot, which usually ends up being lower on the car... typically near a spot where you'd find a factory intercooler on a car (the small ones, not the full ICs).

I agree with the other guy, I would not use the stock piping with these. Unless the car is designed for performance (which Chrysler cars... not so much), there's a very high chance that the stock piping (pretty much all of it) is restrictive.

Oh and my old "Chrysler" 4-banger had 200HP :p. Albeit it was a DSM, which was half Chrysler at the time my car was made, so it counts, damnit. My current Chrysler only has about 145 though, and it's most definitely not nearly as fast or responsive as the other car.

I see we found the village idiot...and he obviously rides a bicycle...:roll:


Just get the whole kit and do it right..;)

how much does the cold air intake improve MPG? Looking to add one but not concerned about performance so to speak as this is a family sedan.

How would warmer air intake necessarily make gas mileage go up? Colder air compresses better, which means it provides less resistance to the push of the piston, which means that there's less energy being wasted on that compression stroke. Not to mention, pre-ignition/knock is FTL.

EDIT: To me, it sounds like you may be mixing up the fact that engines work better when they're warmer or in the case of diesel and low temperatures... work at all.

A properly designed cold air intake can be a good performance investment. I've seen a nice one dynoed on an early 90's GM 3.1L V6 (which only puts out ~140hp stock) and saw nearly a 10hp gain. Then again, I've seen some poor systems on different engines that actually lost power.

If you have that much money to waste, you go right ahead. You will get a slight SOTP feel from the intake, a little better throttle response, and maybe 1-2 MPG. Intakes are a waste of money on most cars and is certainly on yours. But hey, it's your money.

I'll be adding a CAI to my 06 Mustang GT sometime soon, along with a custom tune. Most people are reporting 10-20 HP and a much better throttle response. Most of that is the tune, I'm sure, but the CAI probably adds 3-5 HP when replacing a somewhat restrictive airbox.

And you have a high performance V8 engine. He has an economy four banger.

I think you're going a little too technical.

warmer air = less dense = less (actual) oxygen.
On almost any modern car, the ECU determines how much gasoline actually enters the cylinder. The ECU is programmed to give just enough gas for a perfect burn - ie. all of the oxygen and gasoline is combusted. (actually, I think they're tuned to run a bit on the lean side, but dont' quote me on that) Warmer air would have less oxygen per unit volume, such that the ECU will reduce the amount of gasoline it puts in.

At least that's my reasoning for it.

Aluminum does not rust.

More correctly, aluminum oxidizes on the surface only and the oxidation then protects the underlying metal from any further corrosion. You would have to seriously mistreat a vehicle to get enough gunk under the hood for an aluminum piece to corrode.
