Can anyone please tell me which spark plug they use as a replacement? I've had my 05 500 S for about a year now and I'd like to replace the spark plug. Any recommendations or places to purchase? Thanks!

Is that the same for the Foreman 450?

 

[nonnieselman]

no, the 450 is a NGK DPR7EA-9
optional is NGK DPR6EA-9 (HOTTER PLUG)
optional is NGK DPR8EA-9 (COLDER PLUG)

NGK is differnt from other plug manf.. the higher the number the colder the plug.. BTW.
anybody else need a S-plug PN?

what is the purpose of a hotter or colder plug?

That's what i'm wonderin'. What is better? Which should you run?

 

[nonnieselman]

im not exaclty sure either. but i think it has something to do with detonation and pinging.. but that might be with the timing also? heck i dont know! just run what they suggest.. the middle one.
