plugs?

[drunkenrich]

How often do you guys change your spark plugs? And what brand plug do you like best?

What's the best way to know when they need to be changed? Indicators?

 

[yamaha1973]

I change them when I do carb work (not an option on a nytro) or if they would foul for some reason

I'd change them more often if I was boosted, but otherwise they'll last thousands of miles. Nowadays they last 100k in a vehicle, so even if you were doing them every 10k on the sled, it would likely be overkill.

CR10EK's are popular!

Only time i had to change my plugs is last summer when i was idling it a lot in warm weather. Fouled one out

i changed mine when i do oil,or atleast look at them. i did them this year because i got them for 3$ for 3 plugs.

CR10EKs bi-annually is fine. Advance Auto has them for half the price!
