02 50hp Tracker NGK Spark Plug Question (suppressor or no suppressor)

[nospark1196]

Purchased NGK bpZ8h-n-10 plugs from my local Merc. dealer. All they had in stock was the Z (suppressor/resister) plugs. They could not tell me what the difference was between the two.Should I replace them, or is it OK.

They are more expensive and cut down on noise,static or feedback produced by the electronics. <br /><br />I believe some of the newer Johnson Evinrude product require a resistor/supressor to run properly. <---I know this does not apply to you...but someone else reading it might. <br /><br />TMD

No joke, they are expensive! I spent close to $30 for 3 plugs. Thanks for the help TMD !
