Here are two Napa filters, one a GM specd filter the other a Ford specd filter, same bypass psi and interchangeable. 2100255 Proformer is Vietnam made and has a silicon ADBV, 7502 Gold is China made and has a silicon ADBV. The proformer is the commercial line, is it safe to say the Proformer is the same quality as the Gold? The 7502 baseplate looks to be Premium Guard made.
