The Edelbrock supercharger Stage 1 part #158360 is designed for use with 2018 Ford F150 With Gen III DI/PI 5.0L Coyote engine and 10-Speed Auto trans. The core of this system is the Eaton Gen VI 2650 TVS rotating assembly with a four-lobe design with 170 degrees of twist for maximum flow minimum temperature rise and quiet operation for excellent drivability. We also designed our superchargers with an integrated bypass valve to help eliminate parasitic loss under light throttle improving mileage potential. Our unique and efficient inlet configuration results in a shorter less restrictive intake path for improved airflow without the need for a jack-shaft. Keeping the air cool is a high-capacity air-to-water intercooler and low-temp heat exchanger. The Edelbrock #15836 system is 50-state emissions legal. The supplied tune is intended for completely stock vehicles with the exception of a cat-back exhaust. HANDHELD PROGRAMMER NOT INCLUDED. Supercharger systems sold without tuners are only emissions legal when used with the correct Edelbrock program.
