Halltech 2015-16 Corvette C7 Z06 Stinger-RZ™ has been dyno tested by no less than 20 independent shops, including GM dealerships. They have reported between 40 and 55 RWHP with this CAD developed intake system on the chassis dyno. Installation is the key to getting everything to fit however. Halltech regularly audits the filter box on a spare F-panel to insure a proper fitment. Please watch the video install on our website under Install before purchasing. We highly recommend professional installation. The airbox is sealed, but is much larger than stock to promote better airflow, but it requires moving some of the engine bay components, and some modification. If you are not willing to make these small changes, leave your engine stock. On the other hand, imagine 720 HP at the flywheel, and .41 better 1/4 mile e.t. and +8 mph, which has been reported on the corvette forum. Add the TRIC Ram Air package if you plan on adding that in August. No changes need be made to your Stinger-RZ system to add the Ram Air later.Order ship with our K&N style High Performance filter. Our new green Agapostemon Bee Filter is an available upgrade. Check out the dyno results: 608 RWHP vs the nearest competitor at 598 RWHP.NOTE: the f-panel seal referenced in the installation video is not needed and is thus no longer provided in the kit (you can ignore this step in the instructions).Halltech does not have a CA EO number for this induction system, which means it is not legal for sale in CA, unless used in off-road application,such as track racing.
