K&N 70-1578 Features:

This K&N NextGen Aluminum cold air intake system is engineered for your Ram 1500 V8 5.7L F/I. An American 6063 aluminum rigid tube helps increase the volume of airflow up to 34% to your engine and provides an increase up to 18.9 horsepower and 21 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.
• American Aluminum: Intake tubes are crafted from American 6063 aluminum and finished in Texas.
• Sharper, More Aggressive Sound: The rigid aluminum tube allows the engine’s natural airflow to resonate, producing a race-inspired induction sound.
• Premium Under-Hood Appearance: A gunmetal gray powder-coated finish delivers a clean, distinctive performance look.
• 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.
