The Edelbrock Supercharger System Without Tuner #15270 is designed exclusively for the 2012-18 Jeep Wrangler JK featuring a unique design with minimal components that makes it possible to fit under the stock hood with no cutting or body modifications. At the core of this system is the Eaton Gen VI 1320 TVS rotating assembly with a four-lobe design and 160 degrees of twist for maximum flow, minimum temperature rise and quiet operation for excellent drivability. Horsepower output is 317 at the wheel with 277 ft-lbs of RWTQ (manual transmission). This supercharger has 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. This system #15270 fits 2012-18 JK models but does not include the hand-held programmer or calibration. Complete systems with programmer and calibration are available under part number 1527 for the 2012-14 Jeep Wrangler, and part number 1528 for the 2015-18 Jeep Wrangler.
