hi,
a very basic question:
i'm changing the spark plugs on my new (old) 2L GTX r21. according to the plate on the motor, it wants champion SY 6C plugs. i was reluctantly persuaded by the guy in the garage to buy "uprated" champion EON 3 plugs - because they didn't have the standard ones, and there was nowhere else open... but now i've got the old plugs out, it looks like they have maybe been running a bit hot (?) - the insulator noses are dead white, not a nice tan, the upper electrodes are greyish/white, and no. 4 is covered in white powdery stuff. the new you-beaut plugs promise 'protection against cold fouling' and i am wondering if this means they run hotter than the standard - not good if the standard ones are getting hot, i imagine.... i'd be grateful for any help!
cheers
