Don't buy for Saturn Aura
Benjie4 years agoSweepstakes EntryI bought these because the site recommended these for my 09 saturn aura xr 3.6L 6cyl and I replaced them. My car has worse misfires, low rpm, and terrible gas mileage. Used to give me at least 25 on the highways but I get 8~10 on these. I sent my car to a dealership and they told me that I should replace them with AC Delco (the original spark plugs) ones. I learned my lesson. Always go with OEM parts if you can.Purchased for: 09 Saturn Aura XR 3.6L 6 cylHelpful?
