Air Intakes: K&N vs AirRaid vs ProComp
 

at 4 wheel parts the pro comp air intake system is
$129, while the k & n is $250, and the air raid is
$208.

does anyone know the difference between these? is the
K & N so much more because of it being a 'name brand'?

also, the pro comp and air raid systems say that you
can install with common hand tools. is this the case
with k&n?

thanks in advance,

will

Honestly, you pay for the R&D for K&N. Yes, they do extensive R&D for their
products, and they work as claimed. I don't know about other brands,
specifically, but many are knockoffs made with air cleaners of similar
materials or what have you. If K&N claims they make better fuel economy and
improve performance, you can bank on it.

I just purchased and installed a K&N fipk in my XJ. I've only had it
for less than a week. It was easy to install with hand tools and
everything fit well. I read a lot of ads that said the HP gain was
15-20 HP. There was a power graph with the kit and it said the gain was
5-7 depending on the RPM. I'm still undecided on whether or not it was
a good value. I got mine from Koller Dodge, it was $238. I was very
pleased with the service I got from them. They even shipped it to a
friend to save me shipping and duty fees.

I am absolutely convinced that for a Jeep TJ, neither the AirRaid nor FIPK
do a single solitary good thing in terms of performance. Nada, zilch. I am
convinced they help high-performance muscle cars like Mustangs and Camaros,
but I am TOTALLY convinced they do not help a TJ in the least. Even Jim
Repp, father of the Rubicon, personally told me on the phone that the TJ has
a wide-open air intake system that has more air capacity than the 4.0L
engine is capable of drawing through it, even at WOT and high rpms.

In fact, I would REMOVE my present K&N air filter and re-install my factory
air box if my York OBA wasn't in the way. In the dusty desert wheeling
conditions I wheel in, my K&N was letting fine dust through into the air
intake tube. Not until I installed first a K&N Outerwears prefilter, then
when that wasn't quite enough, a Unifilter oiled foam pre-filter, did my air
tube finally stop collecting dust inside like it never did with the OEM air
filter.

Well, situations vary. First off, the TJ isn't a very hard breathing
vehicle, so it won't benefit as much from the K&N as a muscle car. If K&N
claim 5 to 7 HP increase, that's certainly believable. Now, they may have
used one certain year and model to get that figure and another year, with a
different design will get different results. 5-7 HP isn't very noticable,
unless you can hook up to a dyno and see the results for yourself. Getting
bolt-on HP is a matter of uncorking bottlenecks. If the intake isn't the
bottleneck, your gains are limited.

Mort,
After you have driven your Jeep for a while please let us know your
thoughts. It is comon for people to post their opinions about modifications
here and not have first hand exsperience. Usually it is "a buddy of mine" or
"a guy told me" or it didn't work on a completely different application.

BTW - I would bet that the differnce in cost is a combination of quality and
overhead. K&N is a great product but, how much of the price is because they
sponsor fuel drag cars and NHRA events?

Will, I have installed all three. K&N, Airaid and the ProComp. I find you
get what you pay for.
