Wire conductor, wire length, and diameter help provide maximum spark delivery and protection. Spark plug distributor boot shape and materials provide proper fit, installation, and water-tight seal. Terminal design improves spark plug retention and assists installation with excellent corrosion resistance. Insulator employs high dielectric materials. Coil retainer prevents fretting and micro-arcing.

Useless Spark Plug, Don't Waste Money!

Based on my observations, this spark plug failed to improve my car's performance or gas mileage despite being marketed as a "professional" part... The only upside is that it was easy to install. However, I would not recommend buying this product as there are much better options available on the market..

Pros
  • Durable and reliable, ensuring efficient engine performance.
Cons
  • Not compatible with non-ACDelco ignition systems.

OEM cost with AC Delco

When I ordered online from Revain, I got the same product that a dealer would have supplied, only about $50 cheaper. My car was hiccupping and when I changed the cables not only did the car run smoother but my digital trip meter showed I had used less fuel. AC Delco with your GM product is better every time.

Pros
  • Lots of positive vibes
Cons
  • No power
