anybody ever use k&n or afl performance air filters. do they do what they say they will? meaning better performance or gas milage or both?

 

The only thing they are good for is covering your maf sensor in oil.

In all seriousness, there is a few people who swear by them. I've stuck with OEM filters thus far, and plan on sticking with OEM in the future.

 

I have a K/N drop in filter in my 02 ES. I haven't noticed a difference in performance or gas mileage. Save yourself some money and stick with OEM.

 

u can reuse them by washing them, that's about the only thing good

 

liking these replies!! I've put K&N in several quads, diesel trucks, etc... Lots of claims and maybe they actually work on a dyno by a small fraction, but i can't see any difference operating the unit. PITA to clean. takes almost a day to dry it... then you have to oil it, but not over-oil it....

 

What about FRAM air filters?

I bought one and it feels so cheap like foam and paper. There are less folds than the FRAM filter filter that came with my car.

Is it worth an extra $11 to get an OEM one from the stealership?

 

not sure what I removed from my car...thinking it was OEM toyota filter. I put i n Fram or Purolator...WOW...it is like you describe...flimsy nothing. must be better air flow since there's no filtration!! I think the OEM would be worth the extra $11.
