Who said Yaris was slow?

But for your engine you need to go 1 step colder. Perhaps even 2 steps colder if you are going with high boost (you shoud ask this to your tuner). On NGK the next step colder would be BKR6EIX On NGK, the higher the number , the colder the plug. Heat range 6 is one step colder than a heat range 5. side note: On Denso is the other way around... The Higher the number, the colder the plug. Those should be easy to find on your local auto parts shop. Just go and ask for Yaris Iridium plugs, and then go for one step colder. Just stick with either NGK or Denso. |
