Everything says i need a d8ea. The plug i pulled was a br9es. Its a 14mm thread the d8ea is a a 12mm thread. I know i need a 8 heat range because the 9 fuel fouled. Should i just get a br8es or what?

 

Gonna have to get the BR8ES or get another head so you can fit the correct D8EA plug in. Looks like someone probably stripped the plug out and tapped it to the 14 mm as what I've found shows the D8EA plug also for your model.

 

Exactly what I was thinking, but a second opinion never hurts.
