The gap on the plugs were suppose to be pre set at 0.60 but they were set at 0.40 I set the proper gap installed plugs, truck runs better than it has in years. I have 2004 Silverado 5.3 engine, 122,000 miles. The valves even quit taping. Have been using a differant brand. Just hope these hold up better to water than the brand I was using, because water killed them.

Product was not faulty, plugs were new. Online part matching was incorrect! DON'T TRUST EVERYTHING YOU READ ON THE INTERNET! I went to the store after installation (plugs were in for 30 minutes throwing multiple cylinder misfire codes) and an employee was able to tell me double platinum is not recommended (despite the recommendation from the website) for my 05 2500HD. I needed Iridium. After a quick swap in store and re-install I was on my way with no issues. I would recommend calling into a store prior to purchasing to ensure you have the right plug. I have been doing tune ups for some time now (decades) and this is the first time I have experienced this. I would recommend ACDELCO to a friend as long as they are the right plug.

Comments about ACDelco Professional Double Platinum Spark Plug:

This product keeps my Chevy Silverado 2wd Ltd 1500 5.3 flex fuel in tip top running condition. The are the same as what came with the truck when I purchased it with 4 miles on the truck at the dealer. Can't say anything about fuel to milage ratio because they are the only thing this truck has used for spark plugs. The factory set have 67,000 miles on them they are worn and just started to hesitate while idling. Probably could have cleaned them but I'm heading out on vacation and pulling a trailer hopefully I will see an improvement from 9.5 miles per a gallon to 11 miles per a gallon that would be great. I will edit after we return from our trip.

        Hi Keith, I'm happy to help you! This ACDelco Professional Double Platinum Spark Plug - Part No. 41-962 is pre-gapped at 0.040"-inch from the factory. All the spark plugs are pre-gapped from the factory, the fact remains that the gap must be adjusted for the vehicle that the spark plug is intended for. Those with modified engines must remember that a modified engine with higher compression or forced induction will typically require a smaller gap settings.

        Good question, Bob! This ACDelco Professional Double Platinum Spark Plug (Part No. 41-962) is pre-gapped at 0.04 inch from factory. However, the fact remains that the gap must be adjusted for the vehicle that the spark plug is intended for. Those with modified engines must remember that a modified engine with higher compression or forced induction will typically require a smaller gap settings. When it comes to repairs and maintenance it is always recommended to refer the vehicle owner's manual for the exact specifications.

Since you didn't mention the specific vehicle's year, it's hard to tell for sure. To give you the correct information I would need the year of the vehicle.

        A:

        I'm happy to help, Mark! These ACDelco Professional Double Platinum Spark Plugs (Part No. 41-962 and 41-805) are indicated to fit many of the same vehicles with a gap of .040. Part No. 41-805 is indicated to fit 763 vehicles while Part No. 41-962 is indicated to fit 462 vehicles. The specifications for both plugs are the same and will work equally well in your 2005 GMC Yukon SLT 5.3L V8.

        The GMC Sierra 2500 HD with the 8.1L V8 also has Part No. 41-805 indicated as an Exact Fit with a gap of .060.
