The std airbox with an enlarged front feed & hi-flow panel filter is regarded as best.

However a decent cone filter with a good feed of cool air should be similar. Its hard to get consistant results on a rolling road tbh & the difference would be 1 or 2 bhp, wheras the associated heat problems on rolling roads will cause differences in readings of more than 2 bhp I would guess.

so if i make a decent cold air feed and try and keep as much heat away from the filter i will get a more of a positive result well in theroy i should

thanks for you info CG
