Hey man, don't mess with the whoosh noisesAfter seeing this I tore my factory box apart to see the design. The BMW box is totally sealed from engine heat. The filter is excellent, many large deep folds. Has a large tube going to the front of the grill for cold air. The MST unit can only suck air from the engine compartment.
I did an intake on my STI, I hate those whoosh noises. Returned it to the stock intake after 2 weeks. It's right up there with excessive camber and bolt on flares imo
But to each their own etc.
