2009 Nytro with stock plugs at 3400 miles. When are you changing your plugs and is anyone trying the CR10EK plugs? Are they worth the cash ($8 each) or are stock plugs fine. I put 6000 miles on my 08' Nytro and sold it that way. Pretty funny topic since I changed my 2 stroke plugs all the time.

So what works and when? No misses with my sled, but never know if performance could be ever so slightly dropping off.
 
CR 10 EKs since brand new, 5600 km's and not an issue. I hate saying that because I might jynx myself but...........
 
Hey all I just did a search on the plugs and found a ton of information. I should have done this search first..... Looks like I should get the CR10's and be done with it, I can always use a few more h.p. on a non-turbo sled. Santa might bring me a turbo next year.
 
Can't promise they're going to give you a few extra ponies, but tell Santa where I live to, LOL
 
CR10EK work fine in the Nytro, but you'll never tell the difference. I did them in my Nytro only because I had some left over from my Apex that I hadn't installed. Runs great as usual, but there's no discernible difference in power, and no difference from the original plugs that had 5500 miles on them.
 
save your money and put stock plugs back in....I ran the 10's and couldn't tell at all until I put the SC in and then it ran worse and went back to stock.
 
Has anyone ever tried Bosch Platinum plugs?
