Actually - the HR6DS is a silver tip plug. The HR6DP is the platinum tip plug, or at least it use to be. I used the Platinum plug for many miles and went back to silver because I happen to have a bunch of them and I never noticed any difference. I now have silver plugs that came with the Nology system. Nology claims silver does a better job - I certainly noticed an improvement with the Nology system at least, which is a lot more than just the plugs.
