And do you pre-gap them before install since every manufacturer is made different than the gap for Yaris.

Thanks

FYI, YMMV, I found the price difference between the OEM plugs and the cheapest alternative I could find to be negligible. i don't use the word negligible lightly at all. As Steve Martin's character (George?) in Father of the Bride 2 stated when he didn't want to write Eugene Levy's character a check for $100,000 to cancel the sale of his house (and it was about to be struck by a wrecking ball) - 'You don't understand, I'm the cheapest man in the world'. I laughed because I'm in touch with that way of thinking.
