I know this is a highly opinionated area, but what are the recommendations on high quality air filters? I've done a search (here) and most of what I see is either K&N or paper. Has anyone used the Amsoil EAA122 https://www.amsoil.com/catalog.aspx?code=EAA122-EA? I saw it in a thread and it appears to be the same quality of K&N but much cheaper. Any suggestions will be appreciated!

 

I dont know about that the amsoil one or the k&n but. IMO i would save my money and just get a fram.

 

Purolator. Some studies I looked at a few years ago indicated that they were among the best paper filter for both flow and filtering properties. Some flow better but filter less, some flow worse but filter slightly better. K&N filters flow well but do not do a good job of filtering small particals at all.
Our 97 Explorer had a K&N when we got it and the intake tube (past the filter) was filthy. I cleaned it several times and dirt always got past the filter. My ranger had purolator filters on it all the time and despite tons of time on dirt/gravel/muddy roads my intake tube was always spotless.

 

I have the Amsoil Filter on my Mustang and after 5,000km's (3,000 miles) the oil is still clean....and I beat the hell out of that car, especially at the track.

 

Thanks for the input guys. I've had the K&N in a different vehicle and was never thrilled about the amount of time it takes to re-oil. And I've also read how some people here have had issues with the oiled filters and just don't want to deal with those issues.

 

Yeah after seeing a little grime from a K&N in my intake I went to stock.

 

dang i just put in my kn i dont wanna mess up my engine in yalls experience does it let enough by to cause problems or should i be good

 

The k&n on mine caused surges in the maf which make the truck jump/jolt at low rpms but some people didnt have that problem...

 

hmmm havent noticed it really in mine i dont wanna hurt my engine life though

 

i use a paper wix filter, ive found mud on it before but nothings ever gotten past, since i get them so dirty so often, i replace them several times a year and are pretty cheap
