New Spark Plugs after 166358 Miles

My 2006 Honda Civic EX was probably a bit overdue for new spark plugs. I’d neglected this maintenance item for a while, but at 166358 miles it was long overdue. This evening I picked up four Autolite plugs on the way home and swapped them out. This was considerably easier than I expected.

I only ran into one small problem, when the rubber-lined spark plug socket would remain stuck to the plug deep inside the engine, popping off the extension as I tried to remove all of it. After unsuccessfully attempting to shim the extension in the socket I wrapped one turn of Gaffer’s tape around the assembly (photo) and this problem resolved. All plugs are installed, torqued to spec, with threads coated with copper-based anti-seize. It may have just been coincidental, but the car seemed to start quicker after replacing the plugs. Maybe it’ll run a bit better now, and if I’m lucky maybe I’ll get better mileage…
