a while back i had a 96 maxima se. i had a maf adapter with a k&n cone. it was simply a piece of metal that bolted to where the air box was and allowed for a cone filter to replace the air box while leaving and using all oem intake parts except for the air box itself.
i was looking into it and it seem like they make this for all maximas except for the 7th gen.

any advise on where i could get one for my 2012? or maybe there are previous year adapter kits that will work?

i like the k&n cai but i'd really like to avoid using a non oem part for the section of the intake that the maf connects to.

any advise is appreciated. thanx

 

Check if they have one for the Altimas.
