I use K&N filters in all my vehicles mainly to save money on replacement filters. In addition to saving money on replacement filters, I don't have to wait for the K&N filters to get dirty enough to clean. You can clean them as often as you want and maintain better air flow. K&N doesn't give you dyno results for this product, but even if they did, it wouldn't explain the benefit of this filter. The main difference I see is lack of hesitation in engine speed. When I twisted the throttle with the stock air filter, the engine hesitated before the RPMs increased. With the K&N filter, that hesitation disappears. So even if the dyno results were the same, they bike accelerates quicker simply because it takes less time to get to 3,000 rpm.
