ROUGH COUNTRY Cold Air Intake Kit 4.0L | Jeep Cherokee XJ

The Rough Country Cold Air Intake Kit is specifically designed for the 4.0L engine in the Jeep Cherokee XJ (1991-2001), both 2WD and 4WD. It replaces the restrictive factory airbox with a high-flow system that feeds cooler, denser air into the intake manifold for noticeable horsepower and mid-range torque gains.

• More power and torque: sharper throttle response and stronger pulls.
• High-flow reusable filter: clean, re-oil and reuse for long service life.
• Optimized intake tube: engineered geometry reduces restriction and turbulence.
• Aggressive intake sound: that signature open-intake growl under throttle.
• Bolt-on installation: basic hand tools and you're done in under an hour.

One of the most cost-effective upgrades for your XJ 4.0L. Simple, effective and results you can feel from the first start. Works with the factory ECU, no tuning required.
