As I understand, there is some hp benefit using a K&N air filter. But more importantly has anyone got improved gas mileage using a K&N filter?

Big misconception is that a K&N filter is bolt on peroformance. In reality, it allows an engine to breathe better, giving you more headroom for performance. You likely wont see a significant difference in just slapping one in. Now, don't get me wrong, I have one on my '76 Chevy small block V8 and I love it; Only because for the proper airflow, a regular (cotton or paper) filter would have to be huge to allow the engine to breathe. I'm just letting you know, dont buy it for the wrong reasons thinking that it will suddenly give you a boost to power. Also, they aren't cheap compared to a OEM filter.

I have a 2006 Dodge Ram w/ a Hemi. It's monster on fuel in town and actually quite good on the highway. So even a minor improvement in fuel consumption would be good since a significant part of my driving is in town. The filter would cost $80 and last the life of the truck so there is a long term savings there, but by installing a K&N will the mileage improve? Even 5% would be good.

Yes, it will improve... but not even close to 5%...

The real plus is that you can just wash it out and re-oil it.

It's when those paper filters start collecting dirt that they choke off the airflow... that's when the K&N starts to shine.

It's well worth the invertment... just don't expect to see an improvent in city mileage... that's a hard one to improve on... only your driving style will change that ;)

Don't think your going to get more HP without paying for it, the fuel bill will go up. Atleast thats why I found when I placed one on my 99 Alero, didn't notice any more HP. But DID see a BIG jump on the gas bill.

If you saw a decrease in your mileage, you either changed your driving habit (lead foot), or you have waaaaay too much oil on the filter.

No change, the filter wasn't touched, out of the box into the car. Even after 1 yr I washed it and it was the same thing. Drove it the same way I did before and after the filter.

They vary greatly on application... anywhere from $50 up to $200+

If you want to know how much for your car, call CTC and tell them the make, model, and engine to find out how much one for yours will be ;)

$200???

the highest price ive seen is roughly 120ish. 200+ would be for a new intake system, and not just the filter. but on average they are 70-80.

they will pay for themselves in the long run, since you don't have to replace them, just clean and re oil on every oil change

One some cars you will see a slight difference. On a V8 truck, yeah you'll probably see some gains. On a 1995 sedan? I doubt it. Your best bet in that case is just a good tune up.
