F4I spark plug part number?

[Doodle]

but we are also stunt riders who burn thru tires in single sessions at times..why do we give a rats ass if it gives it a shitty wear pattern...im pretty confident you could ask anyone on here if they notice problems with 190 on 180 rims and vise versa and they will say no.

we are known for running whatever beads to the rim and rocking it.

Hell I run whatever fits too! there is a 190 on my f4i right now... I wouldn't do it on a street bike that I corner hard on though! On a bike that is just in the lot sure, I can adjust for the tire size and still do wheelies. That doesn'tchange the fact that the tire is not the proper shape when on the wrong sized rim....

I completely agree it doesn't matter in the lot. It's effects more that rhe left side of my tire is always worn way down because I can only drift left! lol

get the right ones..it will run MUCH better on idle if you havent changed em in that long.

I used my stock plugs tell 30k miles, no issues.. When I put new ones in, I didn't notice any difference, I just felt better about it..

My friend cheaped out and got some $5 plugs at autozone, after a couple months his f4i ran like garbage.

You MUST run the proper plugs in these motors! I don't know what it is about them, but I wouldn't run anything different. I got my plugs for like $45

You got to consider the fact most people wont change the plugs in their car for over 100k miles! Imo your better sticking to the plugs that came in your bike if you are going to cheap out anyways...

there is no way spark plugs are worth this much arguing
