OP, no Cold Air Inductions?
CAI, Roto, and VR are the three mentioned the most and for good reason. Their gains are consistent. The only drawl back for me with VR was tilting back the radiator. CAI and Roto both are sealed from the engine bay heat. I highly recommend an intake that has some form of seal to close off from the bay.
The cost seems "high", but the intake really comes alive and the bang for your buck really comes when you get a tune done... then add headers and exhaust and the intakes effectiveness is improved drastically.

You read wrong...if this was the case then more than half of the members would not have intake systems. 10-14 hp gains on a stock engine without a tune is great for intake on a stock engine with no other mods. Something CAI, VR, ROTO, all do routinely and have proven in independent testing over stock.
What you may have read is that some webpages have a "GMPP performance intake" which is nothing more than a dress up kit for the exterior of the intake.
