Review on NGK BKR8EIX IX Iridium Spark Plug/Single Piece - Revised for Enhanced SEO by Jonathan Self

Revainrating 5 out of 5

Great forced induction plugs

I use these on my 2010 turbocharged Scion Tc and now they work much better than the OEM plugs. That being said, you should always run 1 or 2 stops colder when boosting your engine. More power = more heat

Pros
  • Great design
Cons
  • Useless features
