Motorcraft, Fram, or Purolator have the K&N statement in their warranty!!

Unlike many companies, our warranty for O/E replacement air filters and intake systems does extend beyond the replacement of a defective K&N part. For the original purchaser of the product, our warranty covers any engine damage or related costs incurred as a direct result of the use of a properly installed and maintained K&N O/E replacement air filter or intake system on the specific vehicle for which the product was designed to be used by K&N. This includes reasonable vehicle repair costs, sensor replacements, car rental fees or other incidental expenses directly related to an engine problem caused by the failure of a K&N product. Furthermore, we warrant that using our product will not result in a vehicle warranty denial. K&N will not be responsible for any indirect, consequential, special, contingent, or other damages not listed above.

We will promptly reimburse the consumer for the cost of the repair if a service provider denies warranty coverage as a result of a K&N product or claims that a K&N product has caused harm to your engine or vehicle. In order to receive reimbursement, we require each of the following:



The consumer must provide a written statement or repair order from the dealership or service provider in which the dealership or service provider blames the problem or warranty denial on a K&N product;
The service provider or consumer must provide K&N with all allegedly damaged parts. Many states have laws that require a service provider to retain all parts replaced during a vehicle repair, unless given consent to dispose of the parts by the consumer. K&N will pay the shipping cost to recover these parts; and
The consumer must provide proof of purchase of the K&N product along with cooperation in helping us investigate the claim.
Once these steps have been completed, K&N will contact the service provider and collect evidence to support their claim. In the event we are not provided with sufficient evidence, we reserve the right to reject the claim and will use our best efforts to assist in establishing your rights toward the service provider under warranty or other provisions.

We strive to exceed consumer expectations. Customer service can be reached at 1-800-858-3333."
I stand corrected, they have changed their warranty statement!!! Thanks!!

I use a K&N filter cause I never have to buy another one...the recharge kit is 10 bucks I bought it 4 years ago when I had a K&N on my mustang and still have enough oil and cleaner to do a couple more charges.

I did a dyno test on one of my other cars...

The K&N cone filter had 2lb feet and 3hp more than a cheap autozone cone filter.

/thread. Again.

So in summary, the only thing that Bob has managed to prove is that his driveway is paved.

Exactly. It was just as pointless as measuring the square footage of each filter. Proved nothing.

I disagree. There is no evidence, photographic or otherwise, that proves the driveway in the photograph is, in fact, Bob's driveway. We can prove that a driveway is paved, but we cannot prove that Bob's driveway is paved.

Ok, I weant a step further today...and took a close up of the filter media, as suggested by a guy on TRS. This tells the story of how the K&N "could" flow more air, with so little filter media area, and it also explains why a K&N doesn't filter well:

?? I don't get it.

so, if I take a close-up picture of a mop pail and a close-up picture of a gold ring, we can take the giant leap that a zinc-coated bucket is worth more than a gold ring?

But again the K&N doesn't rely on the media to filter and trap dust. It relies on OIL! Hence why you have to oil it.

I am not going for one or the other, both are fine if used properly and in the right application, but that is the key.

You take pictures and state your hypothetical, theoretical reasons why K&N doesn't filter well. I have real world experience that indicates whatever level K&N filters, it does it well enough that engines are not harmed by them. Why do you have it out for K&N? Did they step on your toes sometime?

Take a break, you are not saving anybody from anything with this theoretical stuff. If you really want to inform someone about K&N, tell them not to over oil the filters. Also, tell them to make sure the filter seals around the edges well. That will help them much more than what you are doing here.

No, the best thing I can tell them is not to use the K&N! My findings match this independent air filter test....K&N had the lowest filter efficiency:

How many posts like this would you like to see:

But if anyone wants one I have a airraid air system with the conical K&N filter sitting here I will sell ya.

i just took my K&N out of my truck after 25,000 miles....i noticed absolutely no gains over the paper filter, and the cleaning was a pain in the ***. it should be noted im not really shooting for performance in my truck, its just my daily driver

i still run a k&n in my mustang, and ran one in my GTI when i had it

i think they both have their place

Interesting Dan!

I used to have a K&N panel filter on my GTI. I didn't notice any difference over the paper filter but I got the K&N as a christmas gift so I used it. I also bought the re-oiling/cleaner kit.

I only use paper filters now since I don't like the idea of having the oil from a K&N ruining my MAF. My intake tract was always oily in my GTI despite following the directions on the re-oiling kit. I never over oiled it, yet my intake tube and MAF always got oily (no, it wasn't blow-by)

BTW: You should post the cost of each filter.

(140ci / 2 X 5000rpm X 75%ve / 1728) The factory filter has a max flow that exceeds the 152cfm the engine requires. How do I know, well the factory set up is adequate for the 4.0L which requires roughly 248cfm with a lesser 70% ve. Lets give the K&N filter the advantage (yes, sarcasm) of a max flow of 1,000,0000 cfm.

Now for everything to make sense! The 2.3L draws about 152cfm as mentioned earlier. So, it takes 152cfm for the little guy to produce 100hp. The factory filter flows (this is a guess based on the 4.0L figure) 248cfm. The factory filter allows the engine to make its total 100hp while drawing 152cfm while having the ability to flow an additional 96cfm. The K&N unit will allow the engine to make 100hp while drawing 152cfm. The K&N will have the ability to flow an additional 999,848cfm. But wait, the engine can only inhale 152cfm! So what does this mean!? Well, the engine has made no more and no less power than before. If you did something to increase the amount of air the 2.3L requires (TURBO!!!) then yes, a high flow filter would benefit. But for a stock engine, it puts you in the "I wasted my money" group where you can mingle with all the turbonator guys.

huh.

well, my next-door-neighbor knows someone who's cousin's best friend's daughter-in-law's classmate's boyfriend's sister uses K&N filters, and she likes them. You can't get any more first-hand than that!

This may bring no good or helpful info to this thread but its a chance to post a picture.

This is what my intake tube looked like in my ranger. I used a fram paper filter and it had a couple thousand miles on it.( dont know exact mileage)


For the not to smart it should be all black not white.

When I bought my truck I took the K& N out and threw it in the trash, it was sooo oiley and full of dirt and dead bugs.

Istantly my truck ran 10X better and actually idles now, I'll prob put a drop in this summer though for better performance and sound like my last truck had.

To me running a filter that has less filter capacity/ability then OEM is about as smart as removing your mudflaps to "look cool" while throwing rocks at your paint.

Like I stated before, oiling these filters is extremely easy, so easy in fact a person with an IQ of 6 could do it.

Only an idiot would over oil a filter. People who complain about K&N just like to complain. They have sold millions of filters. A company like K&N makes a good product.


**** OEM parts Bob.
