What is the diameter of the ducting going to your ram air set-up? What do you do as far as emissions related inspects because the vac actuator flaps & hot air riser were eliminated? Thanks, Scot

Im not Swervin Ervin, but I might be able to help.

Im not 100% sure, but I think they are 4" diameter (I.D.).

He kept his original air cleaner assy. and puts it on for inspection.

That was my guess.

Eddie is right, it is 4". The first year I had the Ram Air, I put the old air cleaner back on for inspection time. The last two times, I didn't bother and he passed it anyway. As strict as they are around here, go figure.
