Correct me if I am wrong, I am to use NGK BR9ECS plugs in my ( liquid zx chassis ) 2003 MXZ 500? My manual says to use BR9ES but a parts mag and a dealer I talked to said to use the BR9ECS. I talked to somebody at NGK and they said the same. Also to torque them at 18 - 20 lbs/ft? Sound right to you guys?
