So far, oil filter choice does not seem to affect the noise. I have used the following filters on this car:
OEM black Toyko Roki
Blue Honeywell made filter
White "Subaru Canada Six-Star" honeywell filter
Purolator PL14612
Purolator PL14610 (oversized)
Purolator Classic L14460
Quaker State QS14612 (made by Purolator).
Note that this was mostly with different filter/oil combo's so take it with a big grain of salt. (I did do at least one mid-interval filter swap but I'll have to refer my service notes for specifics.)
Oil choice on the other hand does seem to affect the noise. I was surprised by this as all of the oils I have used have all been 5w-30's. So far Castrol Syntec Blend 5w-30 seems to be one of the quieter oils. I'm wondering if it's because Syntec Blend seems to be one of the thicker 5w-30's (11.0 cst@100C whereas most are around the 10.5cst mark.) I was thinking of trying GTX High Mileage 5w-30 next as it's even thicker (12.0 cst@100C).
Anyways, that's been my experience so far trying to quiet the machine down. YMMV.
webfors: Where can you still get the black Tokyo Roki filters?

I bought in with my local subaru club a 1.5 years ago and bought 10 at the time. I don't think you can find them anymore. Next choice Purolator and OEM. Both very good filters. I have 2 more tokyo roki's left, a couple OEM, and 4 Purolators
It'll be a while before I buy new stuff.
