Review on E3 Spark Plugs E3.66 High-Performance Automotive Spark Plug, Single Pack by Jose Schweigert

Revainrating 5 out of 5

Buy it, you will love it

I was skeptical about the flood of advertising in magazines and on television. I tried them luckily they really work, they smoothed out my engines idling and increased my MPG.

Pros
  • Absolutely amazing!
Cons
  • No service
