So far so good

[Bettez88]

So far so good for my little experiment using the Autolite ultra iridium spark plugs in my 09 corolla. Idle seems to to around 800 and kind of shaky, but the car does have 187,000 miles on it. Maybe I’ll throw in the NGK Laser iridium plugs back in idk. Autolite on left, Ngk on right

If you are happy that's all that matters.

Those Corolla's run forever and you are good for another 100 rounds.
