Well it sounds like something to really (not) consider if, as it sounds, there's no discernable difference between having this system function or having it completely removed and disabled. I'll likely remove the whole plenum assembly when I replace my plugs, wires and coils, rather than take it apart to replace the lower plenum, then. Mine's safely taken care of.

Just to be clear, though, for those of you that have had the system both functional and not, there was no difference in low to middle torque? No difference in mileage?
