wich spark plug??

Hi,
I'm getting a new spark plug, what do you recommend a SplitFire platinum or the OEM NGK?

I'm not sure about the platinum type, do they make the engine life shorter?

Thnks ;)

NGK ;)

[TC426EX]

NGK for sure, but there are 2 models to consider...

Stock is a DPR8Z so of course that works great, but I just switched to a DPR9Z. The reason that some switch to this plug is because it is a little cooler plug and helps reduce the temp above the piston in the center of the head. Alot of people run this and I actually think the bike runs a little better with it over the 8Z. Stick with the NGK either way...

thnks tc426ex, anyway, I think I'll get the DPR8Z

see you ;)
