This came off my new to me LS400. Mileage unknown, time unknown but I would guess about 1 year. also opened using harbor freight exhaust cutter, worked ok, same as wix Very similar to the Wix I just cut open except that this filter has a nitrile ADBV instead of silicone. It is difficult to describe the stiffness of the black nitrile ADBV here. It was VERY stiff. Like hockey puck stiff. It would crack in half before it bent in half. Nice wavy pleats, not so important i guess.... but they were very brittle and I could tear them easily with my fingers. this is what it caught in conclusion..... I'm glad I got this piece of junk off the car. And I promise myself to NEVER use a filter with a nitrile ADBV.... only silicone.
