These Napa Filters are comparable to the Mopar MO-452, the Gold is the closets match it however has a silicone ADV and the Mopar has a nitrile ADV, all three of these are a very good filter, built like the Mopar, I would buy any of them, how ever most Proselect and NASCAR Spin-Flo I would only put on a beater car, a couple of years ago they changed construction on most of the Proslect line for the worst when they changed over from calling it "Napa Silver"
