Hi All - For those that are interested, I’ve just fitted some really nice (in my opinion) air filters with 3D printed bodies (as part of my project to eliminate the Air Box).
The three key things I like about these are:
1. AIT Sensor location: The fitment of the Air Intake Temperature (AIT) sensor is integral to the design. Therefore, the sensor is subjected to the fast moving / cooler air that is being drawn into the throttle body (as opposed to simply cable tying the sensor somewhere in the area, which is then subjected to the warmer air being radiated from the engine (and possibly making the ECU think the ambient temperature is warmer than it is, consequently running the AFR leaner than it should; and as we know, these modern bikes run too lean as it is!)
2. The lines! I like how the angle of the filters line up with the frame. It just seems to look cleaner to me.
3. The filters: Top quality water resistant / low maintenance (no need for oil) filters. I believe these are also the same filters used by the Freespirits offer (but the look of those angles just don’t do it for me personally): link
Have I noticed a performance increase? Yes, it does seem to pull stronger, but of course, that could all be psychological due to the increased intake noise (it has a lovely roar at full throttle now!).
Manufactured by VIBA (who created a rather special Bobber - see photo if you haven’t already): link
Available from: link
(great guys to do business with, with some very interesting stuff).
Engine breather filter (ps. I still need to make a location bracket for it yet): link
(with a bit of insulation tape to increase the outside diameter slightly so that the standard pipe fits securely).
Next steps: Wiring / Fuse box tidy up - Apparently, the Arsenale / VIBA team of creating a kit to tidy that whole area up; I’ll keep you posted.
