Yeah, the clamp has 3 1/2" stamped right on it, but is like about 1/16" from being engaged by the adjuster. I didn't measure, so either the clamp is just stamped incorrectly or a 4" is necessary. I tried really hard Mike, really I did!
Thanks for the great feedback guys, i will have to check on the filter clamp, that is the one that comes with the filter when i buy them from my supplier so i could need to replace it with a new one but let me do some checking, as for the kits out there already experiancing this problem i am sure Napa can fix ya up for a buck or two. ;Dr;
