Ok, So today I decided to give the Ready Filter a try, thought it would be a good idea since so many swear by them. I liked the idea of the rubber grommet where the bolt goes through. So why didn't my filter come with one? It showed it in the catalog... Anyways no big deal until I see this fit Now that looks like a world of trouble to me.... I am only lightly pulling back on the filter. Now you can't do that with my No Toil, Twin Air, and stock filter! They have a big hole cut in the center of the filter... like where a grommet would go... so whats up with that? Did they forget to put one in? Either way.... This baby is going right in the garbage!! What a waste of money.
