Search request Spark plugs

My car runs smoothly. I didn't see any flaws in them. I'm not sure if anyone kicked them out because they got four, one had the gap almost completely closed and the other three had a different gap, but it's ok. I found a rebate online for 50 cents each that I will send to AC Delco. I will order again.

Pros
  • Ignition parts
Cons
  • Secret

Standard replacement 1987 Corvette with L98

Installs these on my 1987 Corvette c4 with L98. These are stock plugs and really get your car idling and accelerating just fine again when you have trouble. For me the spark plugs weren't properly spaced, so make sure they're 0.035 spaced if you have a mostly stock L98. Also, be sure to purchase anti-seize lubricant and cap the threads (without touching the electrode) to keep the spark plug from sticking to the engine threads. Makes them safer in the future and easier to remove otherwise youโ€ฆ

Pros
  • Spark plugs and wires
Cons
  • weak
