I weas lurking the Napa site today an realized I should probably look ito buyig cases of filters for my sonata, The Napa Gold filters were 7.69 per filter individually or 7.29 each in a case, but the Napa Proselect filters were 3.29 each individually or 2.29 each for a case. The better deal is clearly the pro select so is there any reason I shouldnt go for this deal? I do 3-5k OCI max so im thinking pro select will be fine.
