What air filters are everyone running?

Anyone have recommendations on what air filter to get if I want to upgrade from the stock one? Air vs Oil? Certain one I should avoid? Thinking about K&N’s filter: https://www.knfilters.com/cold-air-intakes/toyota/4runner/3.4l-v6-gas/1998, any thoughts/recommendations?
I have a 98 3rd gen 4runner sr5 v6.

 

I would stay with OEM.

 

OEM filters are good, but I went with AEM dry filter so I can increase the amount of time a replacement is required.

Stay away from K&N oil based air filters.

 

There really is no upgrade from OEM. Toyota spends millions to get the most MPG and power. The days of easy upgrades are over.

 

Stay away from K&N. Go with a paper filter from a reputable brand as long as it doesn't advertise itself as a high flow or designed for racing since they are designed for performance not protection that we need on 4wd. I use a Napa Gold, it works.

Oiled filters are problematic, they frequently get improperly oiled (if at all), and they aren't suited to very dusty conditions experienced off road. And some people say the oil fouls the MAF, which is probably untrue. Look at Project Farms video on it, they were in distant last place for filtering.

Oil bath air filters that inspired ones like K&N do work in harsh environments. But they are very different in design, and are seen on old tractors and trucks that don't have a maf to worry about.

 

OEM

 

AEM Dryflo

 

Stock. They usually last ten years.

 

NAPA Gold..they are just as good as OEM ones. I buy them every 2-3 years.

 

OEM

 

Doesn't really matter just don't get k & n shit

 

posted this on a separate thread, Can you slap a TRD Filter in the stock CAI filter box? Pros, Cons if it actually fits...

 

I vote OEM
