   GOOD QUALITY PLUG- READ THIS REVIEW BEFORE ORDERING, April 8, 2014

   OK, this is a good quality plug I ordered for my 2005 Silverado Z71 5.3L Vortec. It is the 3rd set of plugs that have been installed including what was in it when new. I have had issues in the past with using other brand plugs so I only use AC/Delco plugs in my GM car and boat engines. Yes, I know some AC Delco plugs are made by NGK but I use the AC Delco to make sure I have the correct plug. They work well and provide a smooth idle on an engine with 244K miles.

   First, I want to let everyone know about a current AC Delco Rebate Promotion good for the entire 2014 year. Rebates range from .50 to 2.00/plug depending on plug purchased. I have not sent my rebate in yet but don’t see why a purchase form Amazon would not be honored. If I have any problems with the rebate I will update this review. Google «delco spark plug rebate 2014» for the rebate form.

   Second I want to address some of the confusion out there about the 41-962 Platinum vs. 41-110 Iridium Plug. If you google «41-962 vs 41-110» the first thing that comes up is AC/Delco Service Bulletin 13D-070. This bulletin clearly states that as of 5/2013 the 41-962 is the correct plug to be used in 2006 and older as well as some 2007 plug applications.

   Without the facts to support this theory I am guessing this means GM 5.3L engines WITHOUT VVT and/or Active Fuel Management which would pretty closely match that model year split so maybe it has something to do with that, I really don’t know what the real reason is they changed the plug recommendation. Some people on the web suggest this change was made because the Platinums are cheaper than Iridiums and this will somehow sell more plugs? They are like 60 cents cheaper each so I am not sure I believe that. I suspect they just found this was a better plug for the application.

   Also, I had the GM Dealer run my VIN and they also show the correct plug to be 41-962

   This is not to say that 41-110 Iridiums will not work in your 2006-down 5.3L engine but according to the people that make these plugs, 41-962 is the correct plug to be using now. In fact 41-110 was PREVIOUSLY the replacement for the original plugs that were in my truck (can’t remember that p/n). In fact, I ran 41-110 from my first plug change at 120K up to about 244K with no problems. There have been reports on the web about people loosing fuel mileage with the 41-110. I am really not sure if I did or not.

   Anyway, I just wanted to clear the air about what is truly the correct plug for the 2006-down 5.3L engines based on AC/Delco’s Service Bulletin.

   Hope this helps!

   Bought these plugs for my 2002 chevy suburban 5.3 vortec 1500, I’m listing all this because there is a lot of reveiws and they are not very clear? I’ve done extensive research and these are the correct replacement plugs for this year chevy and probably the surrounding years. The gap setting on these are .40. Yes the book and the manual says the factory setting is .60 but not for these new plugs!! They come pretty well pre-gapped,but some may need adjustment….a couple of mine were a bit bent? They do come loose in a box and apparently get a little best up like some other reviews say. After installing the plugs I noticed the idle was pretty shaky ? So after some more reading I found from a few car sites that it is wise to disconnect the positive side of the battery after installing so the vehicles computer resets for he new plugs! Believe what you wil, but it worked for me and makes sense….anytime you add, change or replace items like these you should disconnect the battery so the computer will re-boot! Dec. 16, 2013.

   I had E3 plugs in my 2005 4.8l Yukon and had to replace them earlier than what they were rated for, I will never by E3 again! These 41-962 plugs made my truck run good again make sure u disconnect the positive side of the battery to reboot the truck CPU before u start engine.
