The stock plug for the 08 C109r is listed as a NGK CR7EK.
When I go to my local Autozone they list a alternate Bosch Platinum +2 plug part #4303.
Has anyone tried these yet? If so what are your thoughts? ???
NGK
Bosch

I tried a search and couldn't find any step by step instructions on how to change the spark plugs,and what tools I would need. Could anybody help me with this please.
