2020-2024 Ram Gladiator JT/Wrangler JL Cold Air Intake (41843 & 41843-D)

Fits

Give your 3.6L-powered rig the airflow it deserves with the Banks Ram-Air Cold Air Intake System. Whether you're wheeling a Gladiator JT or a Wrangler JL, this system is a massive upgrade over the restrictive factory box, flowing 782 CFM—an 82% gain in total airflow. By delivering cooler, high-pressure air directly to the throttle inlet, Banks provides a 38% air density improvement, giving your engine more thermal headroom and consistent power on hot days or steep climbs.

The heart of this system is the "Big-Ass Filter," which boasts 672 square inches of surface area—21% more than the closest competitor. The durable, fully enclosed housing keeps power-robbing engine heat out, while an integrated Helmholtz resonator ensures an aggressive growl under acceleration without any annoying highway drone. Designed using computational fluid dynamics and torture-tested on the road, the Ram-Air system is built for more miles between cleanings and better performance when the trail gets dusty.
