The K&N NextGen Cold Air Intake (part 50-1564) is a bolt-on replacement for the factory airbox on 2013–2021 Ram 1500 trucks with the 3.6L V6. It uses a black cross-linked polyethylene intake tube and a semi-enclosed NextGen airbox with an enlarged fresh-air inlet, so the engine draws from a cooler, better-protected air source than the stock layout. Owners on user forums often note that the factory system already routes air from outside the engine bay, which makes this kit more of a throttle-response and sound upgrade than a dramatic power package.
Buyers weighing cheaper open-element kits should compare intake designs. Forum members warn that open-air boxes pulling hot air from under the hood can cost power, while a semi-enclosed housing keeps the intake path cooler. The K&N filter also flows more air than a standard paper element, a point owners cite as a reason for the upgrade. Owners on user forums describe modest gains on a stock tune, so pairing it with a tuner or exhaust is the route to a more noticeable change. Confirm your exact model year before ordering, especially for 2019–2024 Ram 1500 Classic applications, since fitment listings disagree.
Fitment listings for this kit disagree on Classic applications, and this product is titled for 2013–2021 trucks. Confirm your exact year, engine, and any emissions-related requirements with the manufacturer before ordering.
Owners on user forums generally report no mileage gain. Some report lower MPG after adding a louder intake, so the kit is best justified by throttle response and sound rather than fuel savings.
