Can you please recommend spark plugs and spark plug wires for my 1993 Chevy Lumina Euro with V6 3.1L engine? Please be as specific as possible. Please provide gap also. Thanks in advance.

Stay away from Bosch plugs and stick with AC Delcos which are the best for GMs.GMs run like crap with Bosch plugs.All Bosch makes is junk and all I hear is bad luck with their products.For plug wires,AC Delco or Carquest's top of the line plug wires.Stay away from AutoZone and Advanced for plug wires,cheap and you want to do it once.AutoZone and Advanced cares about the lowest price only and skip on quality of their parts which fail right away.

Put a fuel filter on the list also and it is a must for a tune up.A plugged fuel filter puts a strain on the fuel pump and will burn the fuel pump if not changed.

AC Delco R44LTSM @.045 gap. I get my wires from NAPA, 8mm.

I'll second the vote for AC/Delco wires and plugs...

Don't be tempted to put platinum plugs in a non-plat application...it never seems to work out well...I've taken more plats out for customers who didn't like them than I've installed (in non-plat applications)

NAPA has nice stuff too, I'll agree with that.
