Cold Air Intake for Jeep Cherokee/Grand Cherokee (1997-2004) 4.0L I6 Engine

Cold Air Intake System for Jeep 4.0L I6 (1997–2004)

Unlock the legendary performance potential of your Jeep 4.0L inline-six with this high-performance cold air intake system, engineered to improve airflow, throttle response, and engine efficiency. Designed as a direct replacement for the restrictive factory air box and intake tube, this system allows your engine to breathe cooler, denser air for measurable performance gains.

Constructed from lightweight T304 aluminum piping, this intake maximizes airflow to the stock intake manifold while maintaining excellent heat resistance and durability. The result is stronger acceleration, improved horsepower and torque, and a deeper, more aggressive intake sound that complements the rugged character Jeep engines are known for.

A high-flow, washable air filter delivers exceptional filtration while reducing restriction. Under normal driving conditions, the filter only requires cleaning every 50,000 miles, saving money on replacement filters over time. Best of all, this intake system installs easily using basic hand tools and does not void your factory warranty, making it a practical and performance-focused upgrade.

Why Upgrade from the Factory Air Box?

Benefits of upgrading include:

• Increased horsepower and torque
• Better acceleration
• Improved fuel efficiency
• Sportier, throaty engine sound
• Reusable filter saves money long-term

Installation Notes

• Installation involves removal of the factory air box only
• Basic tools required (screwdrivers and socket wrenches)
• Most customers complete installation in under 1 hour
• YouTube installation videos are widely available for reference

Tip: After installation, it is recommended to briefly disconnect the battery so the ECU can relearn the increased airflow. Always disconnect the battery before performing engine work.
