Cold Air Intake for Jeep Liberty (2002-2003) 3.7L Engine

Wake Up Your PowerTech V6 with This Jeep Liberty Cold Air Intake

Who It’s For: Designed specifically for 2002-2003 Jeep Liberty (KJ) owners running the 3.7L PowerTech V6 engine who want better throttle response and a more aggressive engine note.

The Problem: The factory air intake on the PowerTech V6 is built for silence, not performance. It uses a restrictive plastic airbox and a ribbed accordion tube that creates turbulence. This design is prone to heat soak, effectively choking the engine of the oxygen it needs to breathe, especially during slow-speed crawling or heavy traffic.

The Solution: This Twin Air Intake system replaces that restrictive plastic with high-quality T304 aluminum piping. By smoothing the path to the throttle body and relocating the filtration point, we reduce intake air temperatures (IATs). Cooler air is denser air, which allows your engine to optimize combustion for better efficiency and power delivery.

Why This is the Ultimate Upgrade

• Enhanced Power Delivery: Real-world gains of up to 10% in horsepower and torque by reducing the pumping losses inherent in the stock PowerTech V6 setup.
• T304 Aluminum Construction: Unlike cheap plastic that cracks over time, this mandrel-bent T304 aluminum piping is lightweight, durable, and dissipates heat much faster than factory components.
• High-Flow Washable Filtration: The included dual-stage filter is designed for maximum surface area. It’s fully washable and reusable, meaning you won’t be buying disposable paper filters every 10,000 miles.
