Hello, getting ready to switch out wires and plugs on 1990 Cutlass Supreme V6 3.1. I have done some searching and it seems like NGK is well liked on the site. Can someone suggest which plug is best? Also, since stock wires are not possible, I was planning on using Napa wires. Would this be advised? Thanks again for any help.

 

How about these wires?

ACDelco Wireset 9706R

 

Why aren't stock wires possible? I have an O'Reilly's set on my 96 98.

For sparkplugs I'd get whatever is cheapest, AC Delcos or Champions.

 

I was saying that I didn't think you could get them from GM.

 

You could go to a dealer and spend big bucks on AC Delco spark plug wires, but any brand from an auto parts store will work just fine.

 

Thank you so much for your help. Ordered some from Oreillys.

 

Have you tried Rock Auto? Lots of choises, and good prices.
