Ruckus plug May 17, 2017 10:04:40 GMT -5 Quote Select PostDeselect PostLink to PostMemberGive GiftBack to Top Post by ruckcanuck on May 17, 2017 10:04:40 GMT -5 Has anyone had to switch to a CR9EH-9 plug to get better running than a stock plug? I do a lot of full throttle running on my Ruck and I believe I need to go to a colder plug.
