K&n air intake system?

Thinking of getting this anyone have any experience with it? Does it help boost fuel mileage? Power? Good bad or ugly I'd like your opinions.

Will gunk up your MAF sensor, and eventually cause problems.

I've had one on my truck for about two years. No issues, but I can't say that it has done anything for mpg. One the noise side, when you jump on it, more noise/sound.....worth it overall????????jury is still out on that one, but I am not unhappy...just not so sure I'd do it again...the lifetime filter does help, tho, one less thing to replace..

I studied the K&N air filters in depth approximately 12 years ago, so I don't know if their technology has changed. But the bottom line is that i didn't install one because i was not convinced that it would stop dust and other particulates from entering the combustion chamber of the engine as well as a good standard filter...ie, less restriction in the K&K means more dust gets through.

I use high quality air filters such as NAPA Gold.

I'm not trying to start an argument here....maybe someone with real technical data on the K&N can chime in... hopefully not someone with a dog in the fight (ie a K&N salesman)

For me the most important function of an air filter is to keep sh*t out

I do like their oil filters

There does appear to be 2 sides to the K&N 'issue'.
I admit that I've have not actually used an oiled filter on an EFI rig, but
have done research on forums like this, and decided against it
because of the MAF problems experienced by others and the
additional hassle of oiling properly. Why some have success with
it and other do not, I don't know.

There are many previous threads on this, including this one:
http://www.tacomaworld.com/forum/1st...n-filters.html

BTW, I ran a oiled K&N on my carbureted 22R about 15 years ago, but took it out after about a year, and went back to stock. Same experience with an aftermarket ignition, which actually failed completely after 18 months. Neither product lived up to the hype.

maybe some folk can read, follow directions...
while others cannot !?

But seriously...
many folk are simply misinformed...

It's the K&N "drop in" filter element for the oem air box
that's more subject to the the over oiling issues.
Because flow design is straight thru, plus a shorter distance to the MAF.

No matter tho'
just because oil residue gets on the MAF does not mean it's ruined.
Nor is it difficult to clean by any means or standards.

There are MAF sprays on the APS's shelves, to clean that.
I'm not paying that much for it tho'
Instead... I use rubbing alcohol and a Qtip (never had issue)

^ I clean off my MAF on occasion whether it needs it or not
basic maintenance keeps performance at its peak.

Ive got a K&N in my 03' Taco. My opinion is its worth it. I have definitely not noticed and increase in MPG, if there is any, its barely anything. The mainly notice the slight HP increase, and the way it sounds when you step on it a little more. I'm glad I bought mine but don't spend your money if you just want increased MPG

i have had mine on for about 5 or 6 years now...

my truck is approaching 300,000 miles with no issue as i clean out the MAF sensor at least once a year...

no MPG gains... i could care less about HP gains as i don't drive fast and furious...

i do notice that the throttle is more responsive with the kit on, so i keep it...

before that, i had the deck plate mod... i didn't notice much difference except for all the little creatures that would crawl into the hole and not figure out how to get back out...

FYI, the drop in K&N has roughly half the surface area of the OEM filter. Its about %50 thinner with 24 pleats vs OEM 22 pleats. The aFe drop in filter retains the OEM size and has similar flow characteristics as the K&N drop in. IMO, the drop in is a waist of money.
