Review on πŸ”Œ E3 Spark Plugs E3.64 Automotive Spark Plug, Single Pack by Dallas Grover

Revainrating 1 out of 5

Garbage plugs don't waste your money!

Total bullshit, no difference in mileage, performance. Put them in my 2012 Cruze 1.4 Turbo before heading to Florida. Drove well until I started climbing the steep hills of West Virginia. Began to misfire and set off a low boost code. I finally replaced them with the stock spark plugs that came with the car after over 100,000 miles and now the car runs like new! GARBAGE! I bought it once and had trouble getting started. I will never take them off again.

Pros
  • Significant potential improvement in fuel efficiency: >4% to 13% depending on engine class
Cons
  • I don't really like it, everything is fine
