There seems to be a lot of confusion about the proper oil filter for the STi at least at this time. Here are pics of the filters.

PN for STi 15208AA080

The shape of the filter effects the oil flow, the filter on the left is for the STi:

Sti installed next to a standard 80 mm filter

The following is a quote from page 8 of the August 2003 Subaru Tech T.I.P.S. newsletter that SOA sends to all Subaru service departments


ALL TURBO MODEL OIL FILTERS

Be advised that the correct oil filter to use on 2003MY/2004MY turbo model vehicles is P/N 15208AA080. This includes the 2004 WRX STi. Naturally aspirated vehicles should use P/N 15208AA024/15208AC060. Using the wrong oil filter on a turbo model may put the filter too close to the turbo down pipe and possibly cause an unnecessary heating of the oil filter.

It seems that Purolator now has an application for the 2.5L motor:

Pure One: PART NUMBER: PL14612

Premium Plus PART NUMBER: L14612

I haven't seen them yet but will post a pic when I do.

According to the WIX cross ref of that number the 51365 WIX filter will work too.

We have BrysImpreza from NASIOC to thank for the following oil filter cross ref:

Hey gang...
after our lengthy discussion on the "new" 080 2004
oil filters, we were prompted to give Subaru a ring
and find out exactly what oil filter is to go where...
and possibly eliminate this confusion.

see: http://forums.nasioc.com/forums/sho...threadid=430542

Our dealership spoke at length with 2 of the
higher - uppers at Subaru
and have the final low down
on this oil filter confusion...
and yes.... they've changed their mind again

As of today, 10/8/03 - we were told the following:

all Subaru Turbo's from 2002 - on
should begin to use the 15208AA080 (black)
as a replacement oil filter.

yes, all 2.0 and 2.5L TURBO's

but....
if you have used or
have purchased the AA060 (white) oil filter -
that is okay!!
You will NOT hurt your car. It's perfectly fine to use the 060
so please, do not panic. Your car will function just fine
with the 060 in place - NO WORRIES

Reason for the change??? ....drumroll please....
.....a manufacturing change.....
yep. different manufacturer <---that is all....

so to keep it simple - Subaru is stating
that ALL MY2002 and newer -
turbo models only - should use AA080

and all NA (non turbo'd) should continue
to use the AA060 (with the exception of the H6, SVX, Loyale...)

hope this helps....
any questions just ask....
