Take your 2015-17 Mustang to the next level with the Edelbrock Stage 2 Supercharger System W/O TUNERR #158390 for the Gen 2 Ford 5.0L Coyote engine. This potent new kit adds huge gains in horsepower and torque over Stage 1 performance, all while maintaining emissions-legal status in all 50 states. At the heart of this system is the top-of-the-line R2650 TVS rotor assembly housed with an integrated high-capacity DP3C (dual-pass, three-core) air-to-water intercooler that lowers incoming air temperatures and increases power potential. To support the additional Stage 2 power increase, the fuel system components are upgraded to include larger 78 lb/hr direct-port injectors along with a drop-in 400 LPH fuel pump assembly with internal check valve. A dramatic increase in airflow over the Stage 1 kit comes from a new 103mm billet aluminum throttle body and high-flow air intake system with 113mm MAF housing. Like our Stage 1 kit for the Mustang, the Stage 2 System installs cleanly with no modifications to the hood or body and comes complete with all hardware, hoses and a handy full-color step-by-step instruction manual to streamline the installation process. This kit is backed by Edelbrock’s industry-leading 3-Year/36,000-mile Powertrain Warranty. For the same kit with tuner, order #15839.
