Q:How many spark plugs do i need?
Steven K.
A:BEST ANSWERHi Steven, I'm glad to assist you. If you have a 4 cylinder engine, you will need 4 of these. If you have a 6 cylinder engine, you will need 6 pieces. For us to accurately identify the correct spark plug set for your vehicle. Please provide the complete information of your vehicle (year, make, model, submodel, engine size, and if 4WD or 2WD). The complete VIN would also be very helpful if you can provide it. I hope this helps. Happy shopping. https://www.carparts.com/spark-plug/ac-delco/ac41-800?can=CPJE1043 Show less
