Performance at its finest. Best Ignition Parts

These spark plugs are amazing. They are made for my type of car. My gas consumption has increased a little and there is power. Excellent value for money and quality.

Pros
  • Durable Finish
Cons
  • Operating Speed

Truck drives great now

These new spark plugs are what my truck originally had. I drove them over a hundred thousand miles before the engine started to die. Patrick D

Cons
  • Out of style

2009 GMC Sierra 4.8L

I just replaced them with Delco quick spark plugs after about 1000 miles and will never put them in my car again. My gas mileage has gone from 17mph to 13, it's just junk plugs for my engine. It might work for you, but certainly not for me.

Pros
  • Confident
Cons
  • Could have chosen a newer model

Take a closer look, not ac delco

Bought by mistake as if they were trying to force you. Same part number as ac delco and they stretched the picture of the plugs so you don't notice the brand isn't delco. Waste of time and money because now I have to send this junk back!

Pros
  • Permanent test results
Cons
