Hey guys, so I was just wonder who on here just has a K&N Air Filter installed, and what kind of MPG gains you get? I installed one a couple months ago. Was on the highway on Friday and was averaging 34mpg, and tonight on my way home on the back roads, after hitting the rest button, I eventually got 23.4. Before the K&N filter I would get roughly 21 on the back roads with out getting on it, and 31 on the highway. Also have any of you experienced any cons with this product?

I put a K&N in the first day I got my car, So I did not notice anything. I ended up taking it out and putting in a CAI and a bunch of other things along with a tune, Once completed I did see better performance and milage. The tune is the key to bring everything together
I have it and have not noticed anything. I really only got it because I only have to clean it once a year or so. Unlike paper, the K&N should still keep the same airflow even when dirty...someone correct me if i am wrong LOL
I tried the JLT cai that didn't require a tune. Although it is a quality product, I had lousy throttle response and hesitation when I punched it. Went back to factory box and KN panel which was ok. I then tried a AFE dry panel filter which has a unique funnel shape that goes deep in the stock box. I also drilled a one inch hole on the bottom right front of box. Results were a seat of the pants difference. Plus my gas mileage went up. I am 68 yrs. on my seventh mustang, just a old school trick that still works.
