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

The Rough Country Cold Air Intake Kit for your Jeep Wrangler TJ 4.0L (1997-2006) replaces the restrictive factory airbox with a high-flow system that feeds cooler, cleaner air to the engine. The result: more horsepower, sharper throttle response and a more aggressive intake sound.

• High-flow filter, reusable and washable.
• Pre-filter included for off-road use, perfect for dusty, muddy or water-crossing conditions.
• Redesigned intake tube for optimized airflow.
• Engineered for the 4.0L engine in the TJ.
• Heavy-duty finish built for serious use.

Installation is straightforward with basic hand tools, with no cutting or permanent modifications required. Clamps, brackets and connections mount on factory locations. In under an hour you will have the kit installed and you will notice the difference from the first start.

A simple, affordable and highly effective upgrade for the TJ, especially if you mix street and trail use. Better performance, better sound and added protection against dirt thanks to the pre-filter. Quality by Rough Country with manufacturer warranty.
