Do not use Bosch 4 tip plugs for coure (toyota)..they are not meant for Japanese Cars...they are purely meant for German babes
[LEFT]I used them on my corolla (i got four 4-tip bosch plugs for around 1000) and it was stupid mistake of putting Bosch. Of course pick and speed performance of the car increased but it reduced the economy and fuel efficiency and as a result engine is getting worse as each day is passing.
NEVER use Bosch "plus" plugs on ANYTHING, try to stick with NGK or Denso plugs on Toyotas.
I recommend OEM or company specified plugs (obliviously companies are not that stupid that they do not recommend over-specifications of any anything)
You should never change brands!
FYI and Fun Fact: The Bush (G.W.bush) family trust owns a large percentage of Bosch
