Mitsubishi Lancer Evolution 4 5 6 High Flow Air Filter Lid Air Intake Upgrade

Airbox Lid for Mitsubishi Lancer Evolution 4 / 5 / 6

The ABCustoms airbox lid for the Mitsubishi Lancer Evolution 4, 5 and 6 replaces the original lid Plug & Play and offers significantly improved airflow. The large, open area with a coarse honeycomb pattern allows considerably more air to pass through than the standard round opening – ideal for performance-enhanced vehicles.

Maximum Airflow for Higher Performance

At power outputs exceeding 500 hp, the original lid becomes a real bottleneck. Our honeycomb lid completely eliminates this constriction and ensures that the engine is optimally supplied at all times. Despite the massive improvement, the design deliberately maintains an OEM look to perfectly integrate into the engine bay.

High-Quality Material – Robust, Heat-Resistant, Lightweight

• Made from carbon fiber reinforced nylon (Nylon CF)
• Very high heat resistance and mechanical stability
• Weight: under 260 g – significantly lighter than OEM
