I am trying to find the recommended plug gap for the NGK YR5 spark plug. Do I need to open up the gap or run .030/.032 gap like used on the UR5 plugs ? See ya! John

Are there any motor builders or tunners out there that even know what I am talking about. I need to know before trying to use them. A few weeks ago I saw a thread but can't find it now .
. Thank you See ya! John

Run the same gap that you ran with the UR5's from what I understand.

Thank you for the information and the shout back. I'll gap them at .028 as I usually run. trying to get this hot air car in the 10's and just seem stuck in the 11.19/11.20. ran 120+ mph my last run of the season then rain and cold weather shut me down. I'll need to wait until March now. See Ya! John
