If you can't get dyno or g-tec, just watch the RPM idling between 1500 to 4500 in 3rd gear and see how fast it does (faster better). it is free to test but I admit it is hard to catch or also with a OBD-2 tester will help to see how is the air flow measures (higher flow better).

You should line the duct with radiant barrier. That will keep heat from the engine from fully going thru.
