Cold Air Intake for Jeep Wrangler SE Sahara Sport X Rubicon 1997-2006 2.5L L4 4.0L V6 Engines

Waken up the legendary inline engine in your TJ and reclaim the performance being choked by that massive, heat-trapping factory plastic air box.

High-Flow Anodized Aluminum Cold Air Intake System for 1997-2006 Jeep Wrangler TJ & LJ (2.5L I4 / 4.0L I6)

Whether you're rocking the bulletproof 4.0L inline-six or the 2.5L four-banger, the factory intake system is a major bottleneck. The stock setup features a restrictive air box and a long, baffled rubber "accordion" tube designed to prioritize silence over airflow. This creates a "dead pedal" delay when you're trying to merge into traffic or power through a steep grade. This kit replaces that 3-foot stretch of plastic with premium 6061-T6 anodized aluminum piping, providing a smooth, high-velocity path for oxygen-rich air to reach your throttle body.

We know the TJ engine bay gets notoriously hot, especially during low-speed rock crawling. The lightweight aluminum piping in this kit helps dissipate heat more effectively than factory plastic, while the chrome mesh high-flow filter maximizes surface area for filtration. This results in a noticeable improvement in throttle response and a deep, aggressive "growl" under acceleration that lets the trail know your Jeep isn't stock. It’s a "Real Talk" solution for the 4.0L—giving the engine the ability to breathe at higher RPMs where the factory box starts to gas out.

This is a complete bolt-on system that requires no additional parts or trips to the hardware store. The included couplers, vacuum hoses, and mounting brackets are engineered to secure the intake piping elbow directly to your throttle body for a leak-free seal. Plus, the micro-cotton filter is fully washable and reusable, meaning you can stop buying those disposable paper filters after every dusty weekend at the OHV park.

Technical Specifications

Why You Need This Upgrade

• Instant Throttle Response: Replaces 3 feet of restrictive rubber and plastic with smooth-bore aluminum to eliminate intake turbulence.
• Signature Inline Sound: Unlocks the deep, throaty intake note of the 4.0L and 2.5L engines that the factory silencer was designed to hide.
• Complete Installation Kit: Includes the MAF sensor adapter (if required for your year), couplers, and brackets for a true no-hassle setup.
• Reusable Efficiency: The high-flow filter can be cleaned and re-installed, saving you money on maintenance for the life of your rig.

Installation & Usage

Installation is a straightforward driveway project that typically takes less than 60 minutes. You will be removing the entire factory air box assembly and the long plastic intake tube. Pro Tip: Always disconnect your negative battery terminal for at least 15 minutes during the install. This forces the Jeep's PCM to reset and "re-learn" the increased airflow values for the best performance and idle quality.

Give your TJ the airflow it deserves and finally hear that legendary inline engine roar.
