well were gonna see if it likes the delcos the 3.1 didn't seem to like the plats. last w/e put fresh wires (210k on originals) and some boch plats my gas milage actually went down.So, today I swapped the plats for some ac delco standard old schools gonna take the ol gpse for a milage run and see if we get back to high 20's some cars likem(plats) some don't
 


I'd stitck with AC Delcos. Either plan, or Rapid Fire. You can open up cans of worms if you use different. There is nothing wrong with Delco plugs.
 
Bosch admitted and I read somewhere that their plugs don't do well in a waste spark setup. Our cars are waste sparkers.
 
thanks,with the experiment the delcos out-perform the plats by about 25% in the fuel milage catagory.....what is waste spark?
