For those of you who run the Puralator Pure One Filter Cartridge, Pep Boys coupon for Buy One Get one Free. They have already pulled it off of their website as I think they made a mistake on it. The filters are $20 each. View attachment 12939 I bought 4 filters yesterday with the coupon on my phone as a photo. For those of you who only run the MC filters, this thread is not for you.
