Halltech's Yellow Jacket™ One Piece Cold Air Induction System is the hottest mod you can add to your 2010-2018 Camaro SS. Dyno tested, we increased the stock Camaro by 16HP/9lbs-ft. Torque. Adding headers too? A dyno done by a customer showed gains of 40 RWHP with only the Halltech Yellow Jacket™ and American Racing Headers/cats onboard. Halltech has built World Class induction systems for Katech Engine Development for over 20 years.
