Seeking Advice on Spark Plugs for 2002 Chevy Silverado

Hey everyone,

I’m looking for some advice regarding the spark plugs for my 2002 Chevrolet Silverado. I want to ensure the best performance and longevity out of my truck, and I’ve been reading a lot about different types of spark plugs available for my model.

Questions I Have:

  • What are the best spark plugs for a 2002 Chevy Silverado?
  • Are there specific brands that I should focus on? I’ve seen Acdelco and NGK mentioned quite a bit.
  • What’s the correct gap size? I don’t want to mess this up during installation.
  • Any installation tips? Should I use anti-seize or lubricant on the threads?
  • Where can I get a good deal on them? Any recommended online retailers or local stores?

Additional Considerations:

I’ve noticed that my truck has been experiencing some misfiring lately, and I suspect it might be related to the spark plugs. It’s also worth mentioning that I haven’t changed them in a while, so I think it’s about time for an upgrade.

Any experiences you could share or any recommendations would be greatly appreciated! Thanks in advance for your help.

Happy driving!

I’m on the hunt for the best spark plugs for my 2002 Chevy Silverado too! What do you think about using iridium over copper? I’ve heard they last longer.

Iridium plugs are definitely pricier, but they offer better performance and longevity. I’d say they’re worth the investment for a Silverado!

I’ve had great success with ACDelco plugs! They’re the OEM choice and fit perfectly with the Silverado. Anyone else have experience with them?

5

Yeah, ACDelco is trusted, but I’ve been told to check the heat range according to my driving style. Any tips, folks?

6

It’s crucial! Make sure to match the heat range to your local climate and how hard you drive. Too hot and they might pre-ignite.

7

What about those split-fire plugs? I’ve seen mixed reviews. Are they worth trying in a Silverado?

8

Split-fire plugs can be hit or miss. I tried them once and didn’t see much improvement over regular plugs. Stick with something proven, like Iridium or ACDelco!

9

Agreed! Sometimes sticking to the classics pays off. Plus, it’s easier for replacement.

10

Has anyone done a comparative cost analysis on the different spark plugs? I’m seriously considering return on investment here!

11

Well, if you plan to keep the truck a long time, investing in iridium might save you money. They last way longer than copper!

12

I think all this talk about iridium plugs makes copper sound like the underdog! Sometimes they still have their place, especially for budget-conscious folks.

13

That’s true! For older models or if you’re just running errands, copper plugs might not be a bad idea.

14

Thanks, everyone! This has helped me narrow down my choices. I’m more inclined toward iridium plugs now after all this input!

If you’re experiencing misfiring or a rough idle in your 2002 Chevy Silverado, it could be a sign your spark plugs need replacing. Check your spark plugs for signs of wear like carbon buildup or cracks.

16

I’ve dealt with poor fuel economy as well, could this be related to worn spark plugs too?

Absolutely, spark plugs can definitely affect fuel economy! When they’re worn, they can’t ignite the fuel as efficiently, leading to that drop in mileage.

That’s good to know! What other symptoms should I look for aside from the misfire and fuel issues?

19

Loss of engine power is another common issue with bad spark plugs. If your Silverado feels sluggish during acceleration, it might be time for a change.

Wow, sounds like I might have a serious issue! Are certain brands of spark plugs better for my Silverado?
