I cut open this Fram Extra Guard PH3506 from my girlfriend's new (to her) '99 Grand Am SE with the 2.4 4-cylinder engine. The filter had just a hair over 3,000 miles on it at the time of the change. It had less than 3 months on the OCI as well, if I remember right. Oil used was bulk Valvoline from the dealership. It looks like the filter did its job, but just barely. The media is horribly distorted, to the point of bending the cardboard endcap in one or two spots. It didn't appear to be separated from the center tube in any spots like Widman's was. The ADBV appeared to be working correctly as there was a bunch of oil in the filter before I cut it open. It makes me slightly nervous to use the Tough Guards I snagged for 50 cents...
