A TB spacer has no real impact on a direct injected motor (MPI, multiport injection) like our. If our Rams were TBI (throttle body injected) then they may help since there is a fuel/air mix that can be better mixed and sped up with the spacer. The only thing going through our intakes is air and a spacer may help, but most reports are that they do not help and are not worth the money. Also, it is very difficult to fit a Gen I K&N with the spacer.

I would have to agree with Jason on this one. The spacer would just be a waste of time and money.
I am not sure about the K&N kit but with my Volant it was a pain to fit in there by it self. If I had any kind of spacer on the Tb it would not have fit.
