bored7one4 Posted July 27, 2005 Share Posted July 27, 2005 what the best spark plug to use? Quote Link to comment Share on other sites More sharing options...
monarch Posted July 27, 2005 Share Posted July 27, 2005 Depends on what's you're definition of best? For best engine reliability and durability use factory original everything - lubes, filters, plugs, plug wires, everything. Your owners manual gives the part numbers for the factory orginal Denso or NGK spark plugs. Quote Link to comment Share on other sites More sharing options...

Yes the plugs are pre-gapped. B) Quote Link to comment Share on other sites More sharing options...
