K&N 50-1578 Features:
This K&N NextGen cold air intake system is engineered for your RAM 1500 V8-5.7L F/I. A high-density polyethylene (HDPE) rotationally molded tube helps increase the volume of airflow by 36.51% to your engine and provides an increase of 19.94 horsepower and 19.93 torque with no tune required. This intake system is paired with a washable, reusable High-Flow LIFETIME Air Filter™ featuring oiled cotton filter media. The oversized, conical design allows you to go up to 100,000 miles between filter services under normal highway driving conditions. A custom designed NextGen air box helps protect intake air from the high temperature of your engine bay, and the entire system can typically be installed in less than 60 minutes.
- Dyno-Proven Performance: Dyno-proven to deliver a guaranteed increase in horsepower and torque on your engine's stock tune. Experience the exciting roar of your engine during acceleration, without any drone at cruising speeds.
- NextGen Airbox: The hybrid airbox features a semi-enclosed airbox that helps lower air temperatures, an enlarged fresh air inlet for improved airflow, and better protection against contaminants.
- Oversized Air Filter: An oversized air filter features an increased surface area and a radius-entry design, both engineered to increase airflow and enhance performance.
- Large-Diameter Tube: The large-diameter, CAD-designed intake tube features strategically positioned air channels that increase airflow, boosting airspeed and delivering more air to your engine for added performance.
- Precision Engineering: Each NextGen intake is precisely engineered for your vehicle, enhancing the style of your engine bay while increasing horsepower, torque, and airflow.
- Simplified Installation: The simplified design reduces mounting hardware, while Quick-Lock™ technology allows the filter to snap into place. A sealing bead secures the system with just one hose clamp.
- 50+ Years of Trusted Protection: Since 1969, K&N filters have delivered superior filtration, extended cleaning intervals, and proven performance, trusted by racers and enthusiasts alike.
