Fast shipping, great prices, what’s not to like.
I ordered a sparkplug and cap for my mini bike on a Friday, and by Thursday of the following week I was riding my mini bike. Fast shipping and great prices keep me coming back.

I'm no expert just got this because it's popular. Engine runs perfect with it in, so I'm happy just knowing that it's an upgrade!

Would...
Never to write reviews but for some odd reason I could really tell the difference switching out the stock plug for the 3910X. I run a 212 pred only with a .32 of a gallon tank, and it’s gotten a lot more efficient. Before switching, I had a full stage 1 upgrade.
