I was wondering if there is any difference, other than the height of the filter? My 75 Corvette used a PF25, which has been superceded by the PF454, but I would rather use a larger filter. I've had nothing but good experiences (except for the PF47 that I can't get off of my buick 
) with AC Delco, so I'd like to stick with them. Will the PF1218 work for me?
