Cold Air Intake for 1991-1995 Jeep Wrangler 2.5L 4.0L Engine

Wake up your square-headlight classic and give that aging AMC powerplant the lung capacity it needs to merge, climb, and conquer.

Performance Short Ram Air Intake for Jeep Wrangler YJ (2.5L / 4.0L)

If you are keeping a 1991-1995 YJ alive, you know that the 4.0L High Output and the 2.5L "Angry Squirrels" are legendary for durability, but they aren't exactly known for their sprinting ability. A major bottleneck in these early 90s rigs is the factory intake tract—a restrictive, baffled plastic setup designed to mute engine noise rather than optimize velocity. This Short Ram Air Intake Kit is the delete button for that inefficiency, replacing the heavy stock plumbing with lightweight, polished T-304 aluminum.

Whether you are running the torque-rich Inline-6 or wringing every last pony out of the 4-cylinder, airflow is king. By streamlining the path to the intake manifold, this kit allows for maximum airflow volume. The "Short Ram" design places the filter for optimal induction velocity, improving throttle response specifically in the low and mid-RPM ranges where these heavy Jeeps spend most of their time. You aren't just getting a shiny tube; you are getting a verified 8-10% bump in horsepower and torque, which can be the difference between maintaining highway speed and downshifting on a grade.

Beyond the dyno numbers, this upgrade changes the personality of the vehicle. The stock airbox silences the induction; this T-304 aluminum tube amplifies it. You will hear a deep, sporty intake growl when you open the throttle, giving your YJ a more aggressive mechanical presence. It’s a complete bolt-on solution that modernizes the breathing of your classic Jeep without requiring permanent modifications.

Why You Need This Upgrade

• Proven Power Gains: Engineering to deliver an 8-10% increase in horsepower and torque by deleting factory restrictions.
• Enhanced Throttle Response: Improves engine reaction in the low-to-mid RPM band, crucial for trail crawling and city driving.
• Premium Construction: Mandrel-bent T-304 aluminum features a chrome polished finish that resists corrosion and dresses up the engine bay.
• Auditory Feedback: Transforms the muted stock idle into an intense, deep sporty sound under load.
• Lifetime Filtration: Includes a high-quality washable and reusable cone air filter, ending the cycle of buying paper disposables.

Installation Notes

This kit is engineered for the DIY enthusiast. It installs with simple hand tools and requires no additional parts or fabrication. The package includes all necessary mounting accessories, couplers, and clamps. Simply remove the factory airbox and tube, and bolt this system in its place. The polished aluminum finish is easy to maintain and looks distinct against the backdrop of the 4.0L or 2.5L block.
