ngk split fire

[2004exrider]

hey just wondering if any of you have used a split fire plug in your 400's and if it is worth it???

I haven't tried them in my 400 but I have tried them in my other quads and trikes. it made them harder to start and really didn't do much else. I run ngk and they seem to work alot better.;)

hey thanks, wonder why it is harder to start though?

The splitfire seemed to make a difference in throttle response when my quad was stock, but once I modded it, it doesn't seem to make a difference.

Splitfires arent worth it and from my experience, dont add a thing. Stick with the NGK and you wont go wrong.

i wouldn't use a split fire plug in anything but a car. Even then it has to be a highly modified one. I like NGK Iridiums for my quads.
