K&N filter - is it worth it?

[Oman350]

Fellas, $60 for a K&N air box filter... is it worth it? My 30k tune up got me a new OEM filter installed, but K&N is making promises that HP goes up (barely) and MPG is better too.

I have a 2014 Runner - ant feed back much appreciated. Also where to buy the darn thing? ... amazon??

Nope. Tried. Lost 1/2MPG. Pay shipping and you can have mine. 89138 is where I'm at.

I second the NOPE. I got a "filtercharger" way back in the day for my V8 Grand Cherokee. I noticed nothing but a more pronounced intake noise. Didn't care for that. The maintenance on the filter (that red liquid that had to be put on every whatever mileage, was a pain in the ass). Never again.

Oh, you gain nothing in mpgs/hp/whatever. You basically get crap.

I had a K&N Filtercharger set-up on my last truck. Aside from the kit coming apart, nothing was gained except a little noise and a PITA.

I'll add another vote for 'nope'. Too much oil on those and you can pretty easily gum up your downstream sensors (ask me how I know). I just order the OEM air filters, as the engineers wanted.

its worth it, if you find it cheaper, also you can get multiple use out of it when cleaning and oiling one right. not too much oil and not too little.

You'd be better off with the TRD Cold Air Intake and and an AEM dry synthetic drop-in filter (https://www.aemintakes.com/dryflow_air_filters.htm).

Be forewarned -- another user on T4R.org drove in dusty conditions and the AEM dry filter he used allowed a noticeable amount of very fine dust to enter the intake. If you don't have really dusty conditions in your area it might work well for you.

I won't ever run one on any of my cars. There was a study somewhere where they compared several air filters, K&N, OEM, Fram, AEM, etc. The K&N ones provide "better power, MPG, etc" by essentially having bigger openings in them is what the results showed. That lets more debris through and into your engine internals. An OEM filter, or high quality paper filter is the way to go. I used to run WIX air filters, but they got really expensive recently, so I've switched to OEM filters instead.

I noticed more low end torque when towing with my Tacoma 4.0. The truck was less likely to hunt for gears. Would I suggest one, no, pain in the ass cleaning. Stick to paper.
