Don't get me wrong - and your car looks great by the way - but Roto-Fab's lack what pretty much every other CAI on the market lacks... a lid, as in an actual airbox that keeps the air coming from a cold spot and not the engine bay... like a CAI should.
The design/function of the ADM Performance CAI is more in line with what a CAI should be.

Again, no flame intended here, to each there own... as long as the owner and the car are happy all is good... but, those that haven't spent the money yet should make an educated decision about the CAI they buy.
