I have usually always switched to K&N when I change my filters. However not for any illusion that I will gain mileage because over 25 years of using the filters on everything I own from motorcycles to my RVs I have NEVER seen an increase in mileage. I am more apt to clean a filter than get in the car and drive to the store to buy another one. Also my Jeep sees lots and lots of dust so I would be going through at least 4 filters a year with it, just makes more sense to use the K&N and clean it when it gets clogged up.

I also don't believe much in the air intake systems. I think for the amount of money you spend on them they are never going to pay you back. From most of the reviews I have seen from others they also claim to feel no real difference in horsepower either. Logically speaking I don't think I could feel a difference from 360hp to 365hp.

I can feel the difference, my wallet is thinner, my butt is closer to the seat, so I can feel the difference, in the seat of my pants. In performance, never. With that said, and I hope you got a chuckle, I believe in K&N filters. After 4 or 5 washings, you have broken even on paper filters. The secret is keep them clean. I clean mine more often than I would change a paper filter. I agree with NWJEEPER on the whole intake system, never going to be worth it.

I have K&N Filters in all of my vehicles including the motorhome. I purchased the Cold Air Intake Kit from Camping World. I had a problem with an installation of my Inverter so I was able to get it just above their cost as a good will jesture. MPG increase much, doubtful, but I will say from a performance side the gas pedal is more responsive. I noticed the difference when climbing up long hills. Before my speeds would drop off rapidly and I'd have to really push down on the pedal to get up the hill. I'm then turning around 4200-4400 RPM, after the install, same hill, speeds maintained longer and I'm climbing at 2800-3200 RPM. Best part is that engine isn't screaming trying to get up the hill. It has to have some positve results in fuel mileage, minimal-yes but being able to pass other trucks on the hills - Priceless!!

This observation was done on Rte 83 in Pennsylvania. I travel this way quite often. I used to dread it for the simple fact of climbing those hills really puts a strain on the engine and my heart as well. Now no big deal! I'm sure there will be some eye rolling about this post but I'm convinced the Cold Air Intake with the K&N, to me, is worth the investment. I paid $335 and did the install myself. I can't put a price on peace of mind. Also No Charge for the Eye Roll I posted for you!!!

Check out this Air Filter Test for some real data. If you can find a problem with this logic let me know.

No arguments with the logic.

My summary of this issue:

1) If you drive in lots of dirty places, buy a high quality washable filter to save money on paper filters and keep dirt out of the engine.

2) If you like toying with engines and have some extra $$, a new air intake with a high quality filter is a simple mod that you can have some fun with.

3) Folks worried about gas mileage are off in the weeds. You want to save gas and have a place to sleep? Ford makes a nice van. The fact that we get over 5 MPG with a 26,000 pound Class A is a MIRACLE that should have us all in awe.

Above all:
