Features & Benefits

ACDelco iridium spark plugs are the latest evolution in high-performance plug electrode material and are designed to last 100,000 miles.

  • Iridium is one of the hardest materials used in spark plugs today, which allows for smaller, more efficient electrode designs for improved cold starting and quicker acceleration
  • One-piece integral suppressor seal helps reduce radio frequency interference, meters spark plug energy to help provide long electrode life, and seals against compression leakage
  • Designed with corrosion-resistant shell
  • Spark gap remains virtually unchanged during the life of the plug

    Good Plugs, NOT GAPPED. Seems to work fine in my 5.3 Silverado

    1 of 1 people found this helpful

    Purchased these plugs with mixed reviews for the 5.3 Vortec. They seem to run well in my Silverado. During my research I saw to NOT gap them, as they come pregapped from the factory. This was not the case. They looked like they had been smashed and every gap needed to be adjusted. Each gap was either way to wide, or way to narrow. To the point of having ZERO gap. Still currently running them, however I did not see any mileage or power increase from any other plug. Probably go back to Platinum after these.

    Pros: Nice plug. Not seriously different. It's a spark plug basically. Had a $2/ea rebate.

    Cons: NOT GAPPED.

    AC Delco 41-110 for 2000 Silverado 5.3

    2 of 2 people found this helpful

    Although autozone did not show this plug as fitting my 2000 5.3 Silverado, other research showed that it did. Replaced plugs and wires and truck seems to have more zip.

    Pros: Price

    Cons: none
