Rough Country Cold Air Intake for Jeep Wrangler JL & Gladiator 3.6L — Reusable Filter, Improved Throttle Response

Rough Country's Cold Air Intake for 2018–2024 Jeep Wrangler JL and Gladiator (3.6L) replaces the restrictive factory intake with a large-diameter tube and reusable filter to deliver quicker throttle response and more usable horsepower.

If your Jeep feels held back by the stock airbox, this intake relocates the filter to draw cooler, denser air from outside the engine bay. Cooler intake air increases oxygen content at combustion, which can improve throttle feel and low-end power without engine modifications. The kit ships with a washable, reusable filter and all hardware needed for a straightforward home install, plus Rough Country’s Limited Lifetime Replacement Warranty for long-term coverage.

How does this intake improve performance on the road?

The larger-diameter tubing and cylindrical filter reduce airflow resistance compared with the factory box, allowing the engine to inhale more air faster. That improved airflow typically results in sharper throttle response and a modest increase in horsepower and torque across the RPM range. No tuning is required for basic installation; the vehicle’s computer adapts to the increased airflow.

• High-flow design reduces intake turbulence and pressure drop
• Cylindrical filter area increases effective filtration surface
• Immediate throttle response improvement after install
• Compatible with stock engine calibration—no tune needed for basic gains

What protection does the air filter provide?

The kit includes a premium, reusable air filter that captures dust and debris while still allowing strong airflow. Because the filter is washable, routine maintenance is inexpensive and keeps filtration performance high over time. Placing the intake away from the hot engine compartment helps limit heat soak and maintains cooler charge air.

• Washable, reusable element for long service life
• Designed to trap harmful particles without choking airflow
• Filter location reduces exposure to engine heat and contaminants

How difficult is installation and what’s in the box?

Installation is designed for DIY enthusiasts and typically completes with common hand tools in a few hours. The kit arrives with the intake tube, mounting hardware, hose clamps, and the reusable filter so no additional parts are usually required. Rough Country provides installation support if questions arise during the process.

• Includes intake tube, filter, clamps, and all necessary hardware
• Standard hand tools are all that’s needed
• Installation instructions and customer support from Rough Country
