Ten engine builder tuners have dyno tested Halltech’s C7 intake. +21 RWHP/14.3 RWT vs. the stock intake system. Bolt on, absolutely no tuning required, guaranteed no codes and no warranty issues. Comes complete with our superflow connector hose, ST-689 cfm filter, roto-molded airbridge, and full instructions. The high velocity design of our rotomolded bridge is designed with taper flow for increased velocity and a true bellmouth radius velocity stack for perfect LTFTs and open loop fuel ratios. 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.
