ROUGH COUNTRY Cold Air Intake Kit 4.0L | Jeep Wrangler TJ

The Rough Country Cold Air Intake Kit for Jeep Wrangler TJ with the 4.0L engine is designed to boost your Jeep's performance by replacing the restrictive factory airbox with a higher-flowing, more efficient intake system.

• More power and torque: increased airflow delivers better combustion and sharper throttle response.
• High-flow reusable filter: just clean and re-oil, no replacement costs.
• Rigid intake tube with optimized design to reduce turbulence.
• Aggressive intake sound under wide-open throttle.
• Plug-and-play installation using factory mounting points, no cutting or permanent modifications required.

Compatible with Jeep Wrangler TJ 4WD (1997-2006) equipped with the 4.0L inline-six engine. Includes all hardware needed and detailed instructions for a driveway install in under an hour.

A simple, affordable upgrade and one of the first mods every TJ enthusiast should make to unleash the true character of their Jeep.
