Air filter Mann or K&N

I bought the K&N replacement filter. I also removed this extra mesh that’s almost like it’s plastic welded on the engine side of your intake. Either way, butt dyno said I gained at least 1hp. And there is a little more intake noise which I like.

I use one in all my vehicles. My partners Subaru is at 130k miles and my Highlander was at 197k miles before i traded it in. Both had no issues and after that many miles in a dusty environment, I certainly saved $$$ by not buying disposable ones.

I bought Mann as my first and Hengst as my second, Mann all day.

The mann is or as someone else said, no real problems using that.

Personally I prefer the mann frecious plus filters due to annoying allergies. Though they are a huge pia to get for whatever reason so I am currently using a cortero filter. Good luck so far

Both are good for oil and air filters. But definitely get charcoal. Made a huge difference for a few more dollars on something you don't change often.

Mann is OE manufacture. When I worked at VW/Audi, our parts department would actually sell those Mann as oe. That’s what customers would get during their 20k services.

There was a "performance" K&N filter and lots of detritus in the bottom of the air box I scrubbed down the box, and it is looking fresh. Except for the super greasy valve covers and rest of the engine bay. Oh, and I'm getting rid of the K&N filter--never been a fan.

Removed the K&Ns for some new paper filters. It'll suck to lose the 10% horsepower gain but I'll try not to die trying to pass Ford Flex's on the highway without it. The air box had a bunch of dirt/scum so I cleaned that out too.

The OEM ones on 3rd Gen Tacomas are better believe it or not. That KN one is going to dirty up quick and mess with your maf sensor.

Thanks for posting this question, mine came with the K&N from the previous owner and the airbox baffles removed. I put them back in along with a new paper filter early on. When that soiled I remembered the K&N was hanging out in a box. Bought a cleaning kit and did my best to follow the directions, removed the air box baffles again (I had at the time recently read about how it may increase flow and improve the sound of the intake), and once clean, popped the 'wet' K&N in.

Fast forward 6k miles and I start having a bit of a rough idle even after all new upgraded ignition components, starter, battery, premixing, and cat delete and so I decided to check the MAF (which I had cleaned back when replacing the SSV solenoid) - fucking filthy! Oil all up in the throttle body. That shit let a mess in there, man! Cleaned the MAF and back to paper we go. Car is healthier than it has been since I have owned it. The intake on the 8 was designed very thoughtfully and very well to run stock components - paper filter and baffles included. I regret messing with it based on old ass posts on RX8club from before the info others have posted here was well understood.
