That in mind, I don't know how good they are. One filter, called the 2876 was half the size of the OE filter it replaced. The 2876 fits several Nissan, Hyundai, Honda, and Mitsubishi cars.
True, went to Tires Plus/Tire Kingdom today and they use same numbering just different letters but gave me the correct, 2808. Lancer can also use 2876 but is much smaller. Both are non ecore and good filters though.
