Short Ram Air Intake for Mitsubishi Outlander (2008-2013) BASE/ ES/ LS/ SE/ XLS with 2.4L Engine Red

Optimizing the 4B12: High-Flow Short Ram Intake for Mitsubishi Outlander 2.4L

Who It’s For: Engineered for Mitsubishi Outlander owners running the 4B12 powerplant who are tired of the stock sluggishness and delayed throttle response found in the factory configuration.

The Symptom: The factory intake on the 4B12 is designed for silence, not performance. It uses a restrictive resonator box and accordion-style tubing that creates massive internal turbulence, effectively choking the engine’s throttle response when you try to merge or pass. Because the Outlander is a heavier chassis, this lack of immediate airflow makes the vehicle feel underpowered during initial acceleration, as the engine has to fight against the vacuum created by the restrictive factory baffles.

The Engineering Fix: This system replaces that restrictive plastic plumbing with a mandrel-bent T304 aluminum tube. By straightening the airflow path and removing factory baffles, we significantly reduce the air drag coefficient. Relocating the filter to allow for a direct draw increases the oxygen density entering the combustion chamber, resulting in a sharper throttle snap and a deeper induction growl that the 2.4L engine was meant to have.

Why Mechanics Choose This Kit

• Enhanced Torque Curve: By improving volumetric efficiency, this kit helps the 4B12 generate more low-end torque, which is essential for moving a boxy crossover with less effort.
• Aggressive Induction Note: Replacing the stock resonators allows the natural sound of the engine to come through, providing a sporty, throaty roar under wide-open throttle.
• Superior Material Science: Built with T304 lightweight aluminum piping and a washable, high-flow cotton media filter that provides better filtration than paper elements while lasting up to 50,000 miles between cleanings.

The Performance Promise

Buy with confidence. This system is designed for a straightforward bolt-on installation that typically takes under 60 minutes with basic hand tools. We recommend disconnecting the battery during install to allow the ECU to recalibrate its fuel trim maps to the new, increased airflow volume. Backed by real automotive experts and fast shipping.
