A true, high-performance air intake system that doesn’t void the manufacturer’s warranty for 5.0L Coyote-equipped S550 2015-newer Ford Mustangs is now available from Granatelli Motor Sports. The PMAS 120mm complete air intake system offers gains of 25 horsepower and 25 foot-pounds of torque and does not require a computer re-flash or expensive custom tune. Each system includes Granatelli/PMAS-calibrated MAF electronics so no flash tool or dyno time is required. Promising to move more air than any other intake on the market, there’s no PVC in Granatelli’s cold air intake. Instead, extensive 3D molding and hours of testing on the flow stand has gone into the design of Granatelli’s new S550 system to make sure air flow is not compromised, and the car’s engine can breathe at its best for maximum performance.
