It's concerning that each Purolator product that Ive opened has shown signs of filter media damage!
The link below was started by member Stu_Rock. The link in his fist post is an Excel spreadsheet that collects all the reported filter tears (Purolator & Bosch) by members on just BITOG. I don't think he has updated it since mid May (his last log-on record), so there have been more reported than what the spreadsheet shows at this time.
