this design; http://i38.tinypic.com/168y6pt.jpg this dyno comparisation was made because the customer complaints about high fuel consumption and low power on a butt dyno. I must say i have tuned this setup w/o filters so the next day he put them himself and called me after a week. I discovered the AFR went from 13:1 (tuned by me) to 11:1 on high revs full throttle :shock:

If he still wants to run a filter element, the ITG full frame filters meant for ITB's work great. Or he can fabricate a plenum/airbox and run a pipe (like a cold-air-intake) to a cone filter. Thank you for posting the results.
