my buddy is going next week for tune i told him stock plugs are best he has se 32186-10 se plugs in it any issues ? for all you tuners that do it every day ?
What year and model bike?
Many of the top tuners would suggest stock plugs/wires.
I've had issues with the SE wires, but not the SE plugs.
Have had a few bikes over the years with the SE plugs that messed with the tach signal on the dyno. Yeah, these plugs look pretty with the little logo but the reality is the stock wires and plugs, or a V-rod plug for a range cooler are more than up to the task for anything running on the street in a twincam application.
