I'd look at the reviews section of this website. Those will give you a good idea of what to expect.

technically the stock routing is a cold air setup, just remove your air silencer, put a K&N box filter in there and it's almost as good. except for smoother piping, that'd be the only advantage i could think of

I've had all three.. went from stock to an underhood k&n conical (got it for free) and I didn't notice a difference. It sounded a little different, but that's about it. The thing with the underhood open filters is they end up sucking in hot air from the engine bay and the fan wash may effect your maf readings. It ends up becoming a hot air intake and hot air=less power. I went to the mac fenderwell system after that and well, it sounds a little different. To be honest I think just removing your air silencer and putting a k&n panel filter would be just as effective as one of the fenderwell systems. They all claim "up to 15 horse" but that's usually on cars where the filter is the weakest link. For a mostly stock engine I don't think it will make much of a difference at all. It sure looks nice, though.

Correct. Unless you just want it for looks I wouldn't waste my money. Now if you're doing some serious mods (h/c/i) I would change to a CAI that has a bigger induction pipe going to the tb. Otherwise just do what bgjohnson said.

That article should be a sticky. Would save newbies a lot of money.

I disagree, i went from stock to cold air induction and really noticed a differnce it felt more powerfull. Your going from a restrictive setup to a free flow one there has to be benifits.

When you say stock, is that stock air filter and silencer?

Well you felt the increase from removing the silencer and changing to a better air filter. If you would've just changed the air filter (k&n) and removed the siliencer you would've felt the same increase minus pretty pipe and the 100+ price tag.

aete - did you read the whole article at the link? It's pretty clear....the stock box IS a cold air set up. What gets in the way are the stock filter being more restrictive and the silencer assembly being flow restrictive. Take out the silencer, and drop in a K&N flat filter, and you've got pretty much the same effect as every cold air kit out there.

As for "it felt more powerful" - well, you'd be surprised at the number of mods that are made that 'feel' more powerful, but when checked via dyno or track times, turn out to be no more powerful, or even less powerful. So seat of the pants testing is questionable at best.

Main thing is not to hang a conical off the end of the maf where it's pulling in hotter underhood air - that's a hp killer to the tune of 1% decrease in power for every 10F degree warmer intake air.

again, i still feel that the cold air kit is better- bigger tubes = more air, and the thing with the filter getting dirty i dont have that problem i clean it once a year thats it, thats all it needs and i check it all the time!

It will only flow as much as the smallest opening, whether its your MAF, TB, intake, etc. Adding a 4" pipe will flow more air until it hits the MAF, where all that air does nothing!

On the dyno we did back to back of a stock box and a MAC fenderwell CAI...

0 rwhp, 0 rwtq!

Yeah...from what I have noticed on mine...well, nothing! I went from K&N and no-silencer to a CAI. Other than MAYBE a slight different sound with WOT, I have not noticed any change. Oh well, the $30 I paid for it is fine...just glad I didn't waste money on a BBK for $150.

And yes, any REAL dyno test of it I have seen shows LITTLE or NO HP gains for a CAI.
