Spark plug wires
 
Can someone tell me a part number for spark plug wires that fit a merc 5.7 liter 1998. I'm hoping I can get some at local parts store?

Ok thank you! Are there any automotive plugs that will cross reference?

I run NGK plugs
Your OEM is a AC MR43T
NGK # is BR6FS , if you want to run those or any parts store can do a crossover for you for about any plug you wish. :)

Sorry I meant to say plug "wires"

No
I wouldn't use auto wires
Marine wires have stainless steel or brass connectors for corrosion resistance
I doubt std plug wires would last long
