So today the new High flow air filter from DNA went into the airbox to compliment the Mistral velocity stack. The stack is an absolute work of art, it’s a crime to hide it away lol. The new filter is claimed to give much better airflow whilst giving increased filtration and can be cleaned and reused. I haven’t ridden the bike with it fitted as yet and imagine there won’t be a very noticeable increase in performance, although when combined with the Mistral decat crossover pipe and Mistral v-boost it would be interesting to know what the actual power increase is. For me the smoother running, better acceleration and much cooler engine temperatures more than justifies the work I have put in.

Its a lovely bit of kit. In a world full of rubbish cheap parts its a real change.
Just comparing the number of flutes on the two filters appears to indicate the original has 60 and the new one 15. That would suggest that the new filter has a quarter of the surface area of the old one. It would be interesting to know how a filter with such a reduced surface area can have a better filtration combined with better air flow. I suspect it has something to do with “absolute filtration” and “nominal filtration”. Does anyone know the answer? Cheers Phil
