Vent: 2020 Sentra spark plugs
Who was the genius who decided to make the spark plug well diameter exactly the diameter of a 14mm deep socket? I had to spray lube on the socket just to make sure it didn't come off of the extension when I was pulling it out. I was twisting and pulling at the same time so it wouldn't come off.
I'm guessing there is some special service tool that has a rubber grommet and is 1mm less in OD.
FYI at about 55k miles, this 2020 had plugs that were a little worn out, more gap than factory spec but I didn't really get in and measure it, just had wiggle room from the feeler gauge I used to gap the new ones. Trying to chase down a hesitation off the line.
