Hey guys just wondering what spark plugs to run in my sled and how many miles do you guys usually get out of them? Ive always been a 2 stroke guy and now I have a four stroke and I'm a little unfamiliar with them. Any info would be great.
m1100 turbo spark plugs

CR9EB. You should be able to change them about every 2500 miles and be just fine.
Are you stock or have power added? On stock we use stock plugs, on reflashes we use CR9EB's at 25 thou, and turbo kits at 20. Not a lot of sleds with 2500 miles on M chassis up here so not many plug changes.
It's a little colder plug and pretty common in turbo applications.

I have 3300 miles on my 13 should I be changing them?
Did a little googeling on my own and came across this info from NGK:
I have slightly modified my engine - do I need a colder plug?
NGK states that "A good rule of thumb is, one Heat Range colder for every 75–100hp added."
