in regards to working with the Selin unit. The MAF's will still measure the air that moves through them and with the proper design to your bracket/velocity stack they should each still receive ~50% of that air despite being combined into a single large filter. The Selin unit should be unnaffected as it will just add/avg the air that goes through the MAF's.
Now I question how these will provide more accurate aiflow measurement as well as increasing power/torque, but the other positives seem valid.
Make sure to do a write-up as there are never enough unique projects posted up for this car.
