Installation is a real pain. Unlike traditional 14x30x1 filters, this one doesn't fit well in the opening. They give you countersunk screws in case the 1/4 screws stick out but honestly you won't need them as the filter is too narrow and installation is a real hassle as you use a grille and have to line it up properly so you can close it . The plastic feels so thin I'm curious how long it will last. The filter is 13.75 inches wide, giving you plenty of clearance. As a result, when you turn on the air conditioner, it sucks in the filter. , which makes a loud bang every time. To fix this, attach Velcro to both short ends. If you paid around $50, K&N took you for a few spins. that the price is not a bad product.
