OK, I have a 04 Civic and currently I'm using a Pureone 14610. The bypass on it looks strange and I'm weary of it. Since the Honda S2000 filter that used to be used on all Hondas is oversized and will fit my Civic I thought I would go look for it's equivalents to check out what their bypass looks like and if it is a spring bypass then I thought I would try one to see. For a Purolator the number is 14459 and any filters that number after Fram is 3593A. So my question is does anybody see a problem with what I wanted to do? And do you guys have any other filter suggestions that will fit and doesn't have the weird looking bypass?
