| Any filter that takes up Volume in the airbox is pants. I can see why some prefer the filtration of undertank types but you can't beat in tube filters for throttle response and power.
Tried the pipercross type that goes between the inlets into the airbox but now use in tube pipercross. The dyno and the Mk1 backside dyno told me that the latter was better for my bike, a 998.
