I'm considering adding a 4inch tube from the grille area into the airbox.It is my belief that with all the entry points into the airbox currently opened there is actually a lowering of the ram effect,so closing those off and cutting a single entry point into the front of the box has to be better.Ill make sure that the top of the airbox fits properly and is sealed with draught excluder or similar to make it airtight...
