ETS 08-16 Mitsubishi Evo X MAF Adapter

This 3½-inch MAF housing and velocity stack give an Evo X intake more airflow and measurement headroom. I'd use it on a higher-power build approaching the useful range of the stock MAF housing. The ECU must be rescaled for the larger housing; it is not a stock-calibration swap. Choose the adapter alone or the coupler/filter package matching the intake tube. The velocity stack uses a 5-inch filter connection.
