OP, thanks for the heads up. How many miles do you have on the filter now? That's some scary chit that the affected filters will fail within 300 miles (at the latest)!!
I just checked my stock, all are S2 (made in Canada) so I lucked out. I've got over 3K miles on the installed filter so I figured it was ok. I already had a close call with a cracked pickup and don't want anymore oil surprises.
This reminds me of the guy on the forums recently who had the dealer do an oil change on his new WRX and soon afterwards he had a big oil leak from the filter causing engine damage. The dealer told him there was an issue with the filter and we were all BS, the tech must've double-gasketed the filter or something. Well, I guess the dealer wasn't BSing after all.
