The Edelbrock E-Force Supercharger system part # 15270 for your 2012-17 Wrangler delivers 303rwhp and 262rwtq for an automatic and 317rwhp and 277rwtq for a manual transmission. This Supercharger is exclusively for the Pentastar 3.6L V6 Engine. Featuring a unique design with minimal components makes it possible to fit an E-Force Supercharger under the stock hood. The core of each system is the Eaton Gen VI 1320 TVS Supercharger rotating assembly with a four lobe design with 160 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 air flow, without the need for a jack-shaft. Keeping the air cool is a high capacity air to water intercooler and low temp heat exchanger. Edelbrock supercharger systems are available in three performance levels for most applications. This unit does NOT come with a programmer or an Edelbrock supplied tune. Supercharger systems sold without tuners are only emissions legal when used with the correct Edelbrock program, which can be downloaded at www.edelbrock.com. For safety, the Edelbrock supplied program will retain the factory vehicle speed limiter setting.
