So about to pick up some spark plugs noticed that RRM kit says use NGK 4469's and gap them to .030 but it seems they are pre gapped to .044 any suggestions on what to use?

 

i gapped mine to .025...just tap the ground electrode gently on a hard surface until the desired gap is achieved...the spark plug measuring tool isn't really necessary, regular old feeler gauges will do...

not sure why they are saying 4469...those are one step hotter than OEM...i would ask for clarification on that one...

 

Thanks crans yeah they said ngk 4469 when I got the parts list from Brandon at RRM

 

generally as you increase power you go with a colder plug...why they are telling you to go with a plug that is hotter than OEM is beyond me...i demand an explanation
