Now that the Chevy Prizm is defunct, is the AC Delco PF1233 discontinued? Or is it specified for the Pontiac Vibe? It seems the last time I looked for Delco PF1233 both places were completely out. Did (does) that filter have an ADBV? I know many chevy engines have it built into the engine so the filter doesnt have one. But then again these cars were toyotas and would need the ADBV. Im thinking I might run the PF1233 on my parents toyotas. At least on the ones where a Ford FL-400S is too hard to fit in the engine compartment.
