Review on ECOGARD XC16108 Premium Cabin Air Filter: Perfect Fit for Nissan Altima, Pathfinder, Infiniti QX4, G20 - 1998-2004 by Kyle Hood

The two filter parts went in easily after removing the glove compartment, but the foam seals glued to the front of the frame were partially torn off by sticking to the plastic packaging when unpacking. The directions also mention the shaded area on the map, but there was no map. I hope the direction of the airflow doesn't matter as they only go one way and the arrow pointed in the opposite direction of the actual airflow in my car (2000 Altima). The product seems to work well but I will try a different brand next time.
