Advance had the exact plugs that had been previously used in the car. They were priced inexpensively, easy to install, and most importantly solved the problem I had with my car.
The customer service was excellent and being able to order online and pick it up at my local store saved me a lot of time. It was great being able to go to the store, pick up my order and be on my way instead of going through the usual make, model, engine routine. I would not hesitate to recommend the in store pickup service to others.

I tried to put these in a GM 3400 and started getting misfires on every cylinder. OE calls for iridium plugs. I put iridium plugs in and all misfires went away. So, the plugs are probably fine if your OE calls for regular plugs but if it calls for iridium then I would avoid using these. I wouldn't have noticed the misfires by driving the car but I have a scan tool and it showed them on every cylinder.

    I've used platinum and iridium plugs and this plug still beats them for the smoothness at idle and power. It seems to hold better in the socket too.

      Comments about ACDelco Conventional Spark Plug:

      My vehicle calls for iridium plugs. I myself do not see a need for these type of plugs. I change plugs every two years in the fall regardless of milage on them. The standard conventional plugs perform really well in my vehicle. Why spend all that extra money. When changing out the plugs the conventional plugs the old looks very good and I keep a few of these incase I get a bad plug but haven't had one yet in last 12 years on this car.

          Hi Killerdexter17, glad to assist you! This spark plug is pre-gapped to 0.060" and would be an exact fit for your 2005 Chevrolet Impala. Replacing the spark plugs and wires depend on the skill level of whoever is removing or replacing the part. Some may have a harder time than others who have experience. I would recommend purchasing a Haynes repair manual specifically for your vehicle. This should be able to assist you further into detail on how to repair and replace specific parts.

      • Q:

        Will this plug make your car run better than an iridium plug?
        Asked on 12/29/2013 by Joe from Michigan

        1 answer

        • CUSTOMER CARE

          A:

          Hi Joe! That's a great question. Copper spark plug conducts better and is generally used in high-performance / modified engines. In a dedicated race cards resistor-less copper plugs are used. Iridium spark plugs are chosen for their longevity only. You shouldn't gap iridium plug because of potential damage to the tips. For that reason and their inferior conductivity, they aren't used in modified engines. Keep in mind their price, as well.
