Spark plug question..... - ZR-1 Net Registry Forums

Vette73 · 06-01-2015

Looking to change plugs soon on my 91...Basically stock except for headers, exhaust and Marc's chip..

I was going to give Marc a ring, but I figure I would ask the members...
Which is a good plug to use? I also read somewhere instead of a .035 gap, you could go with a .050 gap for a little increased performance..

Any suggestions?

Thnx.....JW..
