How many miles does your wife's Camry have on it ? Not changing the spark plugs started to = adverse performance on my '07 at about 203,000-204,000 miles. I ignored that for a few thousand miles and finally had the plugs replaced at about 207,000-208,000 miles. Great improvement.

Doesn't your wife's Camry have at least a 1.8 L (not the 1.5 L the Yaris has) ?

About 120k now. 2.4 liter four cylinder engine. Might do the plugs this spring when it warms up...

A few years ago at a tech meet for my ST1300 motorcycle, I saw an ST13 with 75k miles on the standard plugs. The motor ran flawless. As the local Honda dealer didn't have new ones so we just gapped and reinstalled the old ones.

Bike ran like a watch!

I'd imagine one reason that Toyota recommends replacement at 100k miles is because most owners don't know how to do that.

Why would they lose their factory gap? Never heard of this.

Because the metal of the electrodes literally burns away over time.
