Need advice on plug selection
What brand and number plug do you recommend for 1989 Corvette stock 350, no mod's? Also, what gap? I hear different opinions but thought this is the best forum to get advice. Thanks for your input.

Keep it stock with the stock gap.If you need/want aftermarket,NGK makes a nice plug.I tried alot of others and most do the same.Theres no magic plug except opinions.I like the NGK's for aftermarket because they performed very well in my other GM cars I used them on.
