-----> DENSO VS NGK
my car comes with normal cheap 20 K denso spark plugs
and i think that changing to iridiums would spice things up a little theres the denso iridium power and theres the NGK IX iridium so which one is better? |

Who said Yaris was slow?

Both brands are OEM for Toyota.
Some Yaris come with denso and some with ngk. You can't go wrong with any of them... If there is any difference between those you won't be able to feel it. Denso's are usually more expensive. |

Problem with Iridiums plugs in general is that if you do a lot of idling, short drives, starts and stops, the plugs foul far easier. And they cost a lot too compared to regular plugs.
But the power gains of Iridium plugs are definitely true from my experience. I've seen a lot of logged dyno runs on turbocharged cars that switched from regular plugs to iridium oes and you'll see a smoother power curve, with the iridium equipped cars picking up the odd 2-3, sometimes even 5hp everywhere along the curve. |

splitfires are just a cheep plug, I would never put them in anything I own
our car does not have spark plug cables, it is a coil on plug design
