Can't go wrong with ac delco for gm I have a 03 Chevy avalanche 5.3 and the only thing I would point out is that on the passenger side the last spark plug the wire seems to be shorter that the original, yes plugs and wires were the originals and my truck ran fine until it sat up for 3 years....other than that the plugs are great...waiting on coil packs now ☆☆☆☆☆

Great value. These were the correct platinum plugs for my 2006 GMC with a 5.3L Vortec engine. Check your application as some years/models should use the irridium plugs. The wires were a perfect fit. Again, check your application as, at least for my vehicle, there are two options for wire lengths depending upon the coil set used in your vehicle. These parts had AC Delco or Delco stamped on them.

Any vehicle made by General Motors ( Chevrolet, Cadillac, Buick, GMC, etc) benefit from using AC Delco auto parts. I purchased these AC Delco spark plugs 41-962 for my 1999 Chevrolet Silverado 1500 5.3l V8. I noticed an immediate change, the engine sound and operated more efficiently. I would recommend these spark plugs to anybody that is performing a tune up.

Recently purchased these for a 2003 Silverado 1500 5.3L EXT. Cab Truck. Wires seem to be of good quality and fitment was great! I would buy these again in the future!
