AIRAID Modular Intake Tubes (MIT) optimize airflow to the engine by replacing the factory intake tube. Factory tubes often have accordion-shaped walls, sound-canceling baffles, and undersized tube diameters, all of which hurt airflow. AIRAID MIT kits help straighten and improve airflow to the engine while having a larger opening with a reducer coupler at the turbo. This design enables the tube to easily accommodate future turbo upgrades with larger inlets. The design provides better throttle response and additional horsepower along with better fuel economy.
