    Red face 99 SILVERADO TIME FOR Spark plug, BUT 41-985 replaced by 41-110

    HAPPY NEW YEAR! I HAVE A 99 SILVERADO 1500 4X4 SUPERCAB 5.3 V8, AND I AM GOING TO REPLACE THE SPARK PLUGS... THE ONLINE STORES ALL SAY 41-985, BUT RECENTLY AC DELCO IS REPLACING THAT # WITH THE 41-110. DO WE KNOW WHY? IS IT BETTER OR WORSE?

    BYE THE WAY, I HAVE 180,000 MILES ON MY BABY AND SHE RAN LIKE A TOP. I CHANGED THE FUEL FILTER AND STILL HAVE A LITTLE MISS... GUESS THE SPARK PLUGS BETTER BE CHANGED, BUT I WANTED TO KNOW WHY THE 41-110 IS REPLACING THE 41-985 AND WHICH IS THE BEST ).

    PLEASE ADVISE AND THANKS ! MOLLY
