Is anyone using a K&N air filter? And did you notice any performance/ millage gains? Scotty.

I have one on my Ford 460, class A. Can't say that I have seen improvements that are worth the cost.

Save your money and use the standard paper elements. We had one on a V10 and saw zip dot zero difference in MPG.

Generally they don't improve mileage but they don't filter as well as others either.

That's what I figured but needed to ask. Scotty.

Yep, Have to clean every 50,000 miles, for the life of the vehicle. How many paper filters will you replace over the life of your vehicle? Hmmmm cost savings? Yes, I think so. Anyway, check the dirt coming through the paper vs. the K& N and let me know the ratio differnce. I have these in three of my vehicles and put them in there for more than just the mileage increase. I actually put them in the vehicles I intend to keep running awesome. And, No I don't work for K&N.

I had a K&N in my 97 Itasca Suncruiser. Averaged another 1/2 mpg and a noticeable increase in power going up hills (didn't downshift as often).

We just put in the K/N filter and a larger muffler. (I have to look up the name) Around town we can already see an increase in power. We will be taking the RV to Lake Tahoe in about 2 weeks. To get there we have to go up a grade near our home. I think it is a 7% grade. That will be our test. We will also check mpg. But since we also put on a tow bar and will be pulling a Honda for the first time our figures may be off. Will try to remember to let you know.

Thanks TLH, I have one in my F150 and haven't noticed any increase in millage. I have noticed a slight decrease using the 10% eth. gas though.

One thing to remember is that with a K&N filter you are increasing the amount of air the motor can get. Unless you also increase the amount of air leaving (exhaust) the motor you are not getting the full benifit.
