2006 Ford F-150 Air Intakes

Was trying to save space, It's bulkier than I realized. The box doesn't line up tight with the hole in my fender, 1/2 inch gap there to allow hot engine air in. The radiator housing mount is fine but had to twist the whole box to make other 2 bottom holes line up. But what really has me worried is the intake manifold boot, it seats and clamps on the manifold fine but it needs to be a little longer. It is not a very good seal on the pipe it is just barely on there (and yes it's twisted the right way.) The clamp kept jumping off onto the boot and wouldn't grab nice and tight around the ovalish shape of the pipe. It's on now but if I bump it, it will jump off. I'm very worried about this clamp slipping off while driving and allowing trash straight into my throttle body.
