    Air Filter Extension

    I have the usual riva power filter on my rxp and I was wondering if I'd see any gains by extending it more towards the front of my ski. If so how long of an extension? And pictures are welcome

    Use a 4" tube from the SC to either the front seat intake, or front of the engine with a K&N filter or just use a atrium bird cage in the lowes plumbing section and put an outerwearsracing.com prefilter on it. Call them for dimensions.

    I would like a 4" intake but that riva intake i just bought wasn't cheap has anyone just extended the riva intake to the front of the ski and gained anything? And if I were to make a custom intake would it be better to run it to the front of go to the back by the seat?

    PPG sells an extension for the Riva Power Filter that moves the K&N filter right inside of the air intake in front of the seat.
