The dealer sold me the BR9ES instead of the BR9ECS parts guy told me that those are way better plugs... I haven't put them in yet. What do yo guys think? you know the difference?

You can use either but I still run the BR9ECS plugs.

I ran the br9ecs, couse the conductors, the br9es doesnt fire as clean or as efficient as the br9ecs.

I asked the sales guy for the ECS but he told me that thy don't even carry them anymore cause they had better luck with the other ones... If you can't trust dealer for the right parts who can you really trust?
