Anyone find out for sure if the airfilter is the same between the WRX and the STi?

I checked K&N's web site and they dont have anything listed for Subaru (which seems odd since my brother-inlaw used K&N on his WRX).

Thoughts? Other filters you would recommend?

Beuler, beuler, Beuler?

Anyone? Anyone? ;)

I need to order a K&N for my Landcruiser as well and if I can, I would like to order both at the same time. Can anyone let me know the STi part # for a K&N airfilter?

Agent,

from my post: "I checked K&N's web site and they dont have anything listed for Subaru (which seems odd since my brother-inlaw used K&N on his WRX)." So, I obviously already checked their website.

As to having the part number, I dont expect anyone to have it commited to memory, however if anyone else has been looking for it, they may have found it and could post it.

Sheesh

SupperPupp - I bought and installed a K&N filter on my WRX. It's there on the website, I just checked. Try the website again, it may have had an error in loading...or it could've been that the problem existed between your keyboard and your chair ;) j/k

btw, the part number is 33-2232

Mille grazzie!!

Thanks for the part #, but you may be right, I just tried again and it still doesnt list Subaru. I go to www.knfilter.com, click search by vehicle, select year, select mfg and no Subaru... stand by, let me try 2003 instead of 2004... DOH!! And there you have it. :)

Has anyone confirmed that the STi uses the same filter as the WRX?

Thanks again!

Oh yeah, my WRX is 2003. I'm pretty sure it'll fit the 2004 WRX as both model years share the same airbox. However, it's not exactly clear whether the STi's air filter is the same...maybe you wanna get an intake system, some were talking about the Blitz SUS intake...check here

I sent an email to K&N requesting a part number and got no response. I forgot to check the airbox on my WRX before I sold it. And the autoparts stores are clueless. Wait and see I guess.
