What happens if I install this plug on my 1993 Buick regal 3.8 v6 with a lower gap number other than 0.60?James H.Aug 15, 2023
Best Answer:Hi James, thank you for reaching out. Installing a spark plug with smaller gap can lead to misfire, overheating, and emission issues. This item is incompatible with the 1993 Buick Regal with a 3.8-liter engine. Per checking, we don't have a direct-fit spark plug for your vehicle. Have a nice day.
