The Edelbrock supercharger Stage 1 Street System part #1567 compatible with 2007-2014 Escalade, Escalade ESV, Escalade EXT, Yukon & Yukon XL applications with a 6.2L Gen IV engine. The core of this system is the Eaton Gen VI 2300 TVS 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 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 #1567 system is 50-state emissions legal. The supplied tune is compatible with completely stock vehicles with the exception of a cat-back exhaust.
