Review on NGK 6546 DCPR8EIX Iridium Spark by Bryan King

Revainrating 5 out of 5

NGK candles. a step above the rest!

I installed a set of these end caps on my 2014 HD Iron 883 and day and night the bike revved up. When I removed the standard plugs they didn't meet the clearance specification. Candles NGK Iridium were already supplied with gaps. I have found that after installing these plugs the bike starts easier, seems to run cooler (less lean) and goes through the rev range more easily. Will buy another set if they need replacing would definitely recommend to other Sportster drivers. .

Pros
  • Large selection
Cons
  • So so
