The K&N Engineering 70-1578 NextGen Aluminum Cold Air Intake is engineered for Ram 1500 models equipped with the V8 5.7L engine. Its American-made 6063 aluminum rigid tube is designed to increase airflow volume by up to 34%, with reported gains of up to 18.9 horsepower and 21 lb-ft of torque without requiring a tune.
This system includes a washable and reusable High-Flow LIFETIME Air Filter with oiled cotton filter media. Its oversized conical design can provide up to 100,000 miles between filter services under normal highway driving conditions. A custom-designed NextGen air box helps protect incoming air from high engine-bay temperatures.
The intake system can typically be installed in less than 60 minutes. NextGen intakes are backed by a Lifetime Limited Warranty and are engineered in the USA with dedicated customer support. This product is not CARB approved; applicable emissions requirements should be reviewed before installation.
