Spark plug replacement

[vinny121]

Hi all,

My Yaris engine had a little less power than usual. So I replace the spark plugs at 112K miles although I was hoping that they would last until 120K. I owned a 6 cylinder car and that car's spark plugs had was less wear even at 120K. I am well aware that a 4 cylinder engine takes more abuse but it could be our driving style! Anyway I thought I would share a pic of the worn spark plugs. There is a little bridging occuring on the plug but other than that, I don't see that much wear. I got OEM replacements from Rockauto and installed them the basic way, one at a time. Also I remembered to disconnect the battery so that the ECM can learn the new idling. Our Yaris runs great now. Please let me know your thoughts about any other maintenance that I should do at 112K. I had the coolant flushed at 100K and the transmission fluid looks ok. And I still have the original brakes! BTW, I also replaced the climate control knob bulbs since they went dead. Here is a Rockauto discount code good till the end of October: 1699656514267975.
