You're kidding me, the Mazda parts counter doesn't include the crush washers your Subaru needs?
No, I said it "does not come with a crush washer".
I did not say, "it does not come with a crush washer for my subaru".
Do you guys seriously question why there are less and less new WSC members?
I don't expect a Mazda washer to fit onto a Subaru, then again, I also don't expect a Mazda filter to fit a Subaru.
Yes, the Subaru filters I've bought from the dealership (~3 months ago) had included a crush washer under the plastic wrap.
