Mitsubishi Lancer Evo 4 5 6 High Flow Airbox complete

High-Flow Airbox Set – Lid & Base (Evo 4/5/6)

This set consists of the High-Flow Airbox Lid and the corresponding Airbox Base for the Mitsubishi Lancer Evolution 4, 5, and 6. Both parts were fully developed, designed, and manufactured in-house from heat-resistant, carbon fiber-reinforced nylon. The set is ideal for performance-enhanced vehicles where the original airbox becomes a bottleneck.

High-Flow Lid – Maximum Airflow

The lid replaces the original airbox lid in a plug & play manner. The large opening area with a coarse honeycomb pattern allows significantly higher airflow than the standard small round opening. This lid is strongly recommended for vehicles with approximately 500+ hp, as the OEM lid has been proven to be a flow restriction.

• Extremely lightweight lid – under 260 g
• OEM-oriented look, but significantly optimized function
• Heat-resistant & stable thanks to Nylon CF
• Designed for vehicles with MAF or MAP setups

Base with 80mm or 4" Connection

The optimized base offers an aerodynamically efficient 80mm or 4-inch connection for high-performance intake systems. It can be installed as an alternative to the OEM base or in combination with the High-Flow Lid for maximum performance.

• Plug & Play fit for Evo 4/5/6 without MAF
• MAF-Delete: ideal for MAP-based setups
• Aerodynamically efficient transition from box to connection
• Compatible with High-Flow Lid & OEM Lid

Optimal Solution for Significant Performance Upgrades

This set is ideal for power levels above 500 hp.
