Cold Air Intake for 1993-1998 Jeep Cherokee 4.0L Inline-6 Engine

Waken up the legendary 4.0L High Output engine and reclaim the performance being choked by that restrictive, heat-soaking factory plastic air box.

High-Velocity T-306 Aluminum Cold Air Intake for 1993-1998 Jeep Cherokee XJ (4.0L I6)

The 4.0L inline-six is a tank of an engine, but the factory intake system on the 1993-1998 XJ 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, which creates a "dead pedal" delay when you're trying to merge or climb a steep trail. This kit replaces that restrictive path with T-306 high-quality finished aluminum piping, providing a smooth, high-velocity path for oxygen-rich air to reach your throttle body.

We know the XJ engine bay gets notoriously hot, especially during slow-speed crawling where "heat soak" kills your low-end torque. The lightweight aluminum piping in this kit helps dissipate heat more effectively than factory plastic, while the high-flow cone filter increases the surface area for filtration. This results in a 6-10% increase in horsepower and up to 8% more torque—essential gains when you're turning larger tires or hauling gear. Plus, you finally get to hear the signature deep, throaty growl of the 4.0L that the factory silencer was designed to hide.

This is a complete bolt-on system designed to fit both automatic and manual transmissions without any permanent modifications to your rig. The included micro-cotton filter is fully washable and reusable, meaning you can stop buying those disposable paper filters after every dusty weekend at the trail. Everything you need—from the vacuum hoses and reducers to the MAF adapter—is included in the box for a true "no-trip-to-the-parts-store" installation.

Technical Specifications

Why You Need This Upgrade

• Instant Throttle Response: Replaces the "accordion" intake tube with smooth aluminum to eliminate turbulence and improve engine reaction time.
• Reclaim Lost Power: Specifically engineered to draw in denser, cooler air for a more explosive combustion cycle and higher torque output.
• Lifetime Filter: Stop wasting money on paper filters; this high-flow unit is washable and reusable for the life of your Cherokee.
• Signature 4.0L Sound: Unlocks a deep, aggressive engine note under heavy acceleration while maintaining a clean, professional look under the hood.

Installation & Usage

Installation is a straightforward driveway project that typically takes less than 60 minutes with basic hand tools. You will be removing the bulky factory air box assembly and the stock intake ducting. 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 fuel economy gains.

Give your XJ the airflow it deserves and finally hear that legendary inline-six roar.
