Predator 212 hemi
Found this plug while searching for a stage 1 kit for my predator 212 hemi, the plug itself runs a lot smoother and makes it easier to pull start, i run my predator 212 in 30° weather and it always starts first pull with this plug as with the stock plug it would take 3-4 pulls while having to play with the throttle.

Great spark plugs at the lowest price
I accidentally ordered 2 sets of spark plugs bc i forgot to check my emails of all the crazy stuff i ordered. The go power sports are the lowest price that i could find and i over paid on the other website. Either way go power sports is still my favorite. John and ike led me in the right direction. I wanna go re-re fast!
