Terrible Spark Plug, Failed Tests

This spark plug is a complete waste of money. As an automotive enthusiast, i expected better from this brand. As my tests showed this spark plug failed to produce consistent sparks. It even caused engine misfires, making my car run rough. The only positive point I can think of is its affordable price, but it`s not worth the hassle. Save yourself from frustration and go for a different brand. .

Pros
  • Affordable
Cons
  • Failed tests, caused engine misfires
