Part 2 of our multi part performance upgrade dyno test. This video documents the back to back dyno testing of a stock 2005 Harley Davidson Duece. Part 2 add's a K&N 1499 stock style replacement air filter as well as NGK Iridium plugs. Dyno testing shows another dramatic gain in peformance after it's installation by Chris Waddell of cyclesolutionsonline.com and boxoflube.com. This bike is not tuned yet and the only other mod is a set of Vance and Hines pipes that were on it to begin with.

I notice a prominent K&N patch on your shoulder, and you showed us how easy it was to change. And darned if it didn't show a signifigant improvement. The thing is you also changed the spark plugs, and didn't show us how to do that in a jiffy. If one wasn't paying attention they might be inclined to credit the gain in power to the filter, for all we know it hurt power and the plugs helped more then the filter hurt. Pfft, get real and show us what that filter really does.
