[Guest aiya4]

Just a normal few bucks plugs is good enough. Comparing the prices we can change a few times more to those $20 plugs.

Think it's just logical that if you buy a plug too hot for your bike, confirm pop hole in piston one.

 

Just "downgraded" to some $9 Denso plug.

But haven't go webby and see the specs yet.

[E-DEAD]

i understand that using too good plug will cause piston crack or ... unless you got MOD Piston ... ! it will cause it !

[merz65]

last time using spitfire normal plugs.. $8 per plug.. nothing bad happen..

now using NGK R fro LAB $7.50 per plug.. think i'll change back to spitfire feel its more reliable than NGK R fro LAB..

[it wasnt me]

 

heat intensity leads to lean burn out....that applies for extreme case....

 

As for Super4...stick to the OEM spark plugs.....and of course stick to the stock heat ratings....

am i right to say that using any plugs with too high a heat rating will cause that?

[IST]

Me too, now using spitfire plug and the feeling is good.

[ekin101]

I should be using denso spark plug. $6 per piece.

[Guest ~deNso_iRidiUm~]
