All of five minutes and all you need is your fingers!

Don't forget to affix the sticker to the airbox, lest some yahoo throw your filter out and replace it with a paper one... And charge you for it! Don't laugh, it's happened to someone here.

Hey so how often should you change the K&N filter I got one and also the recharger kit but am not sure how to check if it is dirty. Do you go by mileage or just put it up to the light and see if you can see through it.

love it.

You should actually get more of a performance boost from a cat-back exhaust than from the K&N.

It takes a LOT for the K&N to be "truly dirty" and it actually works better when it's dirty.

However, when it's all nasty looking, use the kit to clean and consequently re-oil the filter and you'll be ready for tens of thousands more miles and smiles.

I finally got my K&N today after O'Reilly ordered it for me. I've been reading these threads for a while, so I couldn't wait to get it installed. The first thing I did was take the truck out for a spin, and I DID notice a difference in the pickup and acceleration. Of course, that may just be observer bias. Anyway, I keep very detailed records of my gas mileage, and I'll post the numbers after I have gone through a few tanks of gas with the new filter. From what I have seen in other threads, the difference is probably statistically significant, even if it doesn't amount to much in day-to-day driving. The interesting thing would be to compare the cost of the K&N to the paper filters over time, then factor in the gas savings.
