400ex plug

[SuperEX]

What kind of plug are you guys running? And is a splitfire worth the extra couple of dollars?

im runin spitfire...... for 6 bucks its worth it

Naw Splitfire isn't worth it. IMO

Not really a better plug out there than the NGK.

NGK is 1 dollar at my local honda shop, and the spitfire is 6. The only difference is the spitfire is pre-gapped. That only takes like 3 minutes to change though. I wood much rather spend 3 minutes saving 5$ rather than wasting it. After NGK is correctly gapped then it runs just as good as the spitfire if not better.

I agree ngk, the only thing I did was go I step down in heat range.

What do you meen by "pre-gapped"?

[Dienamo111]

In my opinion I have ran both ngk and splitfire and to me it seemed like ngk just wasnt all the way there for me, splitfire has ran really well so far and I have only had one, since I have owned the bike, so my final decision is probably going to be splitfire........... Just my opinion though! Do some research on both to get a better idea!:square
