I have the Halltech.
IMO only replacing the filter does not help as much as a replacement CAI due to the OEM intake tube sound baffles which interrupt linear airflow into the throttle body in favor of sound reduction.

Matt at Dedicated Motorsports ran back to back tests on intakes recently. I think it was a C7Z but the best combo was a halltech intake with a green filter, which happens to be the same combo we've used in house and had great results. Not in for debate just throwing the info out.

On the Z06 there is not much debate pick a drop in filter or a Cali and there is gains for sure with the supercharger but the LT1 different story. Makes sense they use the same intake for both cars so must be choked up on the Z06 or we got all the intake we need lol

This is a little off subject, but while waiting for service on my car I was checking out the dealers inventory of new Corvettes, One of the cars noted in the optional equipment column that it included the new GM performance air intake system for $ 595.00, with a note stating it was a dealer installed option.

I have very limited experience with the C7 platform but the shop ran by a friend sees some intakes suffer more from heatsoak so take that into consideration.
Very consistent and simple gains do come from a ported throttle body and a filter like BMS' drop in.
It's a bit more power everywhere with no heat soak so it stays consistent.

David I seen you had a Vararam on order so when you say waste of money please be more informative. Did you receive intake and not like it or just putting a drop in with a ported throttle body. Thanks

Folks have stated they got dyno gains just from removing the plastic piece that covers a hole directly over the air box located on the fender by the hood hinge , is this because it reduced the restrictions or because it allows the stock air setup to pull cold air from the same place the Vararam is pulling from .... dont know ....

David , no cold air or air cleaner will add HP unless there is a restriction like on a Z06 but what the Vararam did for me was lower my IAT on my LT1 enough to stop the ECM from pulling timing and allowed the engine to produce all the power it is supposed to make . A car on a dyno with fans blowing on it s not going to show this gain . I can only speak to my experience on both my C6 and now on my C7 . Is it better at not allowing heat transfer thru the tube , is it because its pulling air from the area by the hood fender seam , dont know but what I can say is I log every run I do at the drag strip along with weather conditions, 60 ft times etc and I have seen a huge improvement in my times

The Cold air kit I was referring to was the Jake piece GM makes and sell for $625, only the airbox.

No not that guy , there was a post here where a guy posted back to back dyno results, if you open your hood and look on the passenger side right by the air intake , right at the joint between the fender and front bumper there is a plastic piece that is snapped into a hole in the fender , that is what he removed
I could not place what he was taking off so I went out to the garage and looked at my car and sure enough on both sides is this black plastic cover , when u unsnap it there are two holes that lead right into the air box
