I was waiting for my wife to finish shopping the other day so I was reading a D-Sport article on the Evo X and they added a K&N drop in filter, a 3" design craft exhaust, and royal purple motor oil 5W-30 to yield 36 awhp. What I found curious with the filter and exhaust it brought the dyno from 293 awhp to 300 awhp. So 7 awhp from royal purple might be worth me changing my oil sooner. I was planning to use royal purple anyways since that is what I run in my Ion Redline. Anybody have any experience with royal purple and the X?
