  • Spark Plugs - What's Running?

    What spark plugs do you run in your car? I personally run Denso Iridiums with Denso wires.

    I'm kinda guessing that they're AC Delco on a new(er) GM vehicle. The engine compartment in my car (Cadillac STS V8) is shrouded to the point that all you can see is the dipstick so it may not have any plugs at all AFAIK

      NGK Irids here.

      Probably a waste of money, but it make me sleep better at night!

          Factory (Other) in the Roush, and the cheap Autolite Coppers in the truck.

                I still have the factory ones with 50k miles. I was going to change them this fall but it looked too big of a job for me and I didn't have time. From BlueLibby04's post maybe I should change mine pretty soon. lol

                  Same here...the Liberty has 37k on it now...can't imagine what they look like, but no problems from them so far.

                    NGK iridiums in the Corvette and NGK G-power platinums in my wife's Honda.

                    I did notice a difference in throttle response on the Vette when I switched to NGK iridiums from NGK copper plugs. It was very slight, but definitely there. It seems to fire up a split second quicker on cold starts now too. (not that it took a long time before)

                      Bosch Platinums in my F-150, probably go to NGK's when I change them

                        Re: Spark Plugs - What's Running?

                        Since two other Liberty owners posted in here, I want to say you need to make SURE you used compressed air to blow out from around the plugs before you take the plug out but after youve taken the coil off. I blew tons of sand and **** out which would of fallen down into the engine when the plug was taken out.

                        Check this thread that I made:

                        This was alittle more involved than I thought it was going to be. For one thing, having a lifted Jeep with bigger tires makes it a pain in the rear to work on anything in the engine bay. This was the first time working on it with the new tires on it and I can tell a big difference. Three on...

                          Yea...I might want to look at that considering almost all the off-roading we do is in the desert/dunes. I know how much sand comes out from the under body...I have the absolute worst luck with screwing things, honestly I strip almost everything I try to screw in, its a genetics thing or something. So I think I'll just take it to the dealer ship and have them mess it up...

                              Thanks BlueLibby! I emailed the link to myself, maybe I'll give it a go this winter.
