I bought an extra one not realizing the previous owner had one and instead of trying to return it my friend just bought an 06 altima se-r so i was just curious if it'd work in his car. Id imagine it'd be a pretty similar setup but wasn't sure.

it would make more sense to ask the Altima crowd... I dont see why anyone here would know what fits their car

Won't, traded in my 05 SE-R Altima for my "G". Won't fit. I had a Injen CAI.... NOPE!

i should of specified that its a drop in filter that I was referring too

nm it fits

Same part numbers for both cars for the drop in.

LOOK up the app on K&N's website.... it'll take you 2 minutes!

If they have the same part numbers your in luck!
