Air filter for 2005 Legacy 2.5i

#1 (**permalink**) 09-12-2006, 03:42 AM

Hello,

Can someone let me know the cross reference for the Subaru Engine Air
filter? I had seen in a FRAM reference that it's a CA4309. This is
*not* the correct one (not even the same size). I also see that WIX has
an air filter (#46914). FRAM also has a CA9113, but I'm not 100% sure
this is the right one either. An Autozone told me that was a match, but
I have doubts.
Then there's K&N filters 33-2304, but they are $35-80 each. Are they
that much better than the cheaper FRAM/WIX filters? I know with the K&N
part you can clean out the filter when it gets dirty, but to they
really offer that much better of performance/mileage?

Have considered an online OEM dealer? there are a few good ones. I have
used www.subarugenuineparts.com a coupla times and been pleased.

I dunno the answer to the Fram number issue. seems odd - but '05 I guess
is still a little new. maybe the website has an updated chart?

When all is evaluated I found the OEM to be the best value. As Carl
suggested you can try on line but, for a small order it may not be
worth the time & effort.

I ended up ordering the K&N air filter from ajusa.com (33-2304). I
think it was about $38 or $39.
