My dad said a guy he met a guy today who has a 05 F150 5.4 and stuff and he said he got a K&N air filter, just the filter not the intake and he noticed more power and 2mpg! When my dad told me I was like there is no way! Would ya'll think that could help that much?

 

I did not see any MPG gain when I added mine.

 

Nope, just a filter, not really..

 

no mpg gain, but it did seem a bit more willing to move.

 

Oh, he said he got it for about 28 bucks on amazon and noticed 2mpg increase and more power! Hmmmm my dads buying one for his 01 to try it..

 

I have just the filter in my truck and I didn't really notice any gain. If there was a gain...it was small. I bought it because I only have to buy one filter and it should last the life of the truck...any added benefits like mpg or hp would just be icing on the cake.

 

Idk, all the stuff like K&N post and stuff says designed to gain horsepower,air flow, gas mileage, hell my dad bought one for his truck I think he's gonna buy me one for my truck

 

It's all in the head if the power is felt. Not really any mpg gain here; just cheaper in the long run. I have actually dug into it alot and it seems that paper filters are better and cleaner so....... i will be switching back

 

IMO, the main benefit of running a K&N or similar type filter is that it's washable and reusable. That's it. Power gains are negligible. Get one of those fancy smancy rigs with the replacement tube and conical style filter if you're out for power gains.

 

All I know is I get low 12 like 12.1 and like 11.8mpg in the city and I NEVER take it past 2100K rpm from a start and i got 2wd!

 

I get like 14-15ish around town and 17-18 on the highway, although most of my daily commute is highway. Once in a blue moon, when the planets align properly and the Earth's magnetic field is going my way, slingshotting my truck down the road, I can break 20 mpg. 12 mpg in the city ain't necessarily unrealistic for these trucks. Ain't good, ain't abnormal either.

 

2wd truck getting 12? thumper gets like 14+ I think! he's got 35s and 4x4! :O

 

I dont ever get that kind of bad mileage, even when im into it...

 

Rub it in why don't you! I'm thinkin when it gets more miles on it it'll get better has 2750 and it turns 1 year old July 12th!

 

It's only got 2700 miles? Geez man, drive it some more and re-evaluate your fuel mileage afterwards.

Looking back above, the 12 mpg thing was probably a dumbass thing for me to say; I average 11-12 mpg foot to the floor most of the time with a trailer running back and forth to Texas. Plays hell with my fuel trims when I get back to driving "normal" though.
