Have always wondered from a engineering standpoint, how and if any, filtration of intake air is achieved >6000 RPM's on the SVT DSI setup. Considering it's common use in off road events where dust and dirt are being stirred up when the DSI activates, from my rudimentary understanding of the system the air intake filter is effectively bypassed, allowing this dirty air to enter the engine and begin decomposition of the rings/cylinder walls. Engineering oversight? Any ideas??
