Any of you use those K&N air filters? Any thoughts on them?
I was thinking about buying one for the stock replacement on my 2 bbl, but since I'm going to get a remanufactured engine with a 4 bbl (Hopefully next year) was thinking about getting a generic 14" filter and housing and using a reducer so as to fit a 2 bbl for right now... Don't wanna buy 2 of them...
Anyway, is the $40-45 price tag for the filter worth it? Any noticeable benefits at all? I notice that all the motorcycle guys seem to use them....

for your carbureted engine it should help in increasing airflow....k&n air filters allow alot more air to pass thru than crappy paper filters
get one man you won't regret it...it'll sound nice too
the only bad thing about k&n filters is with the newer hemi engine...people have reported loss of mpg with them on the hemi...apparently the hemi is already aspirated quite well from the factory....personally i'm running a true flow foam filter in my truck...an 04 hemi

Hokie Smokes man! ... How do you close the hood?? :D :D :D
I talked to a guy in town that builds hot-rod motorcycles and he swears by them also... but he also said that he almost always has to go up 2-3 sizes in main jets on the carbs, because so much air is getting through it leans the mixture out... I'm going to assume that this isn't a problem on a V8? (I'm only going by that my truck seems to run as well without an air filter as it does with one...)
What about the actual 'dirt catching' abilities? Any insights? I ask because it's a mile and a half dirt road to/from the house and I do a lot of 'off roading' around here. Very dirty and dusty. Plus I'd rather ask guys who actually use them rather than advertising new-speak...
(BTW Mopower, when my engine grows up, it wants to look just like yours.. ) :D

I have no problems with it....Then again ......The Wagon hasn't seen a trail in a LONG-LONG time......But there guaranteed to a million miles....& if you buy a paper one every three thousand miles you'll be money ahead if you buy one!
I just stick in the sink and wash it with some soapy water, Rinse with hot water (From the inside out) then allow to dry....or blow it dry with the compressor (again from the inside out) Then reapply the K&N brand filter oil & your done!!
Slicker than snot!!!!

Well let's see. Same size as stock, allows more air flow(thier claim)air flow contains dust. I don't know.

Hmmmm...
Two 'Go for it!'s
And two 'dunno's' .....
Although I can see the $$ side of it... A Napa 'Gold' air filter costs $7.00 ... So even if you change the filter every 6,000 miles... (Which I'll bet few of us do..) At $40.00, a K&N filter would pay for itself at about 37,000 miles...
Not bad...
Now so far as being better at catching turds, birds and bacteria and everything else in between, than your regular paper filter... I dunno either.
(Funny story here... About trying to keep crap OUT of your engine... When I was a freshman in high school ... 1969 ... And I was taking auto-shop, I was shocked to see the teacher one day, bent over the fender of a rig with a fresh-rebuilt engine.... revving the hell out of it and sprinkling talcum powder down the throat of the carb... He told me that it would seat the rings in... FAST.
He may have been right, but I'd never do that to an engine I paid for.. ;) )

I installed the K&N on my 88 D50, and one of my crown vics,,an 86.....see no difference....BUT, on some other forums, they have test results that do show the K&N does flow more dirt, according to oil samples.....Would I install another one,?? NO...I`m gong back to the WIX>.... also, some complaints on different forums concerning oil contamination of the MAF computer systems......The K&N i put on my 88 Ram 50, w/ the 2.6, did not yield me one fraction of better gas mileage, course this is w/ a carb on this engine.....Just my experience .......

I plan on putting a 14x4 K&N on my engine once its done... I'm gonna keep the same size paper filter that i have if i can ever get it to a dyno to get some real numbers (i doubt you'll be able to notice anything).... But, from what everyone has told me... they last a long time.

I used them on my racecars (a.k.a. my babies), only exception is if rules say no, then I consider cheating. I can't swear to any HP gain but if it helps the engine breathe better I'll do it. Same for keeping the air cleaner. Just be sure you do the maintenance (clean & oil) - may be easy to forget on a street vehicle.

Don't forget to add in the cost of the recharge kits for the K&N

I have one in my Ram Van and did notice a bit more power, but not much in such a heavy vehicle.
I also put one in my wife's '03 Monte Carlo SS and I can tell quite a bit of difference in power.
I think they're pretty good filters in my judgement although I haven't done any dyno tests.

There can be one problem with K&N filters on fuel injected vehicles. The oil on the filter can migrate up into the MAF, or MAP sensor. The oil can cause problems with the sensor reporting the proper pressure to the ECU. That, in turn, throws off the fuel injection and the engine can start to lope/miss-fire.

^^ Not a problem on most Chryslers, since they're almost all carbed or Speed-Density EFI.

My buddy tried it on his Omni GLHS, junkyard engine w/ new rings. He used a little too much and the fuel hit it, packed it up and locked the engine down:thatfunny

I had the stock replacement K&N on my '99 Dakota 318. There was no noticable difference in either performance or mileage. I won't buy another.

If you are keeping your OEM enclosed air filter housing, I don't see a benefit, since the throat on the intake will limit the amount of air coming through. If you go with an open housing, then it will increase the amount of air flow whether you have a paper filter or K&N, especially if you increase the diameter and height for more surface area. Comparing the air flow of paper vs cotton is like blowing through a paper napkin vs blowing through a cotton t-shirt, there is a big difference.
