K & N air filters

What say you?

I have heard a lot of positives about increased hp and gas mileage, but I also had someone tell me that they will eventually mess up the air flow sensor due to the oil build up from the recharge kits.

In my experience, a complete CAI can give modest increases, very modest, and a little more with exhaust & tune mods. The oil contamination is only a problem if the filter is not prepped correctly, over oiled & not dried. They are easy to clean and oil. I ran one in a recent car, a drop in, and it was perfect after 35k, cleaned & oiled every 10k.

Don't waste your money. Our engines dont require a "high flow" filter. Not to mention the K&N lets in a lot more dirt than a good paper filter and in an off road vehicle dust and dirt is everywhere!

Oh, yeah, definitely get a K&N filter. It is the WAY TO GO(tm)!!

Some of us has modifed our air intakes do be dual air intakes - that way we can run TWO K&N filters at the same time and trap twice the dirt!!

K&N is super duper. Get one! Or make the above mod and get two!!!

After about page 2 of that thread it became a p**s-ing context. Not looking for an argument or smart *** comments, just opinions of whether they are good or bad.

If you read that entire thread, in between all the pissing contest, you'll find arguments for and against. And in the end, there was no real yes/no answer. Basically, you're going to have to decide for yourself- you won't find the answer on this forum.

as you said: just opinions of whether they are good or bad. That thread is full of both opinions.

And that's the real lesson of the thread - it's become a religious debate here.

Bottom line is that I've not seen issues with oil screwing up the MAF, but others say they do. And I actually don't have one in the Jeep, because just a filter element will do little to nothing for your performance. Even a full CAI is really just a dress on a pig IMO.

But I do use them on my Corvette, where airflow is king for me. Heck, I even took out the MAF screen to get better flow, but entirely different beast. Been doing that for the life of the car, which I've had since new in 1996. So I do think they are good filters, just maybe not for every application.

My $0.02 is on the Jeep, they aren't really worth the coin, but if you went ahead and did it anyway, you'll probably be fine.

Besides, according to some here, you'll apparently notice a lot more problems with the big honking boulders they let into your engine well before the sensor gets oiled up enough to matter.

actually, they handle the boulders fine... it's that fairy dust they allow thru which allows users to suddenly get an additional 5mpg and 20hp at the wheel

Somebody tell the part again about having to buy the washing/ re-oiling kit. That's my favorite part!!!

If you hook your K&N up to your main reflector dish, you can emit a tachyon burst. It doesn't do anything for engine performance, but it can make that trail ahead of your a bit more passable.

Can we talk about synthetic vs dino oil now? I liked my K & N but for dirt use I'd rather see a real oiled foam al-la dirt bikes. Dirt bikes have em availabletoo but they are not catching on very well. Another maker is introducing a version that looks similar and claims to have lived thru Baja IIRC with no dirt passing thru???Anyone done that, modded a dirt style oiled foam? Paper has its flaws too, but it is hard to dismiss you can get em anywhere and they are comparatively cheap.

Dino oil is the way to go, don't waste your money on synthetics, you'll still have to change it every 6000 anyway for the warranty.
