Time to replace worn spark plugs! I bought iridium plugs for longer lifespan and better fuel economy.

Assemble the Spark Plug Spanner!






I used a heavy duty 1/2inch drive and spark plug deep socket to remove and install the plugs. The extension bar is specifically for getting at spark plugs since it allows for a wobble with the socket.

Installation is the reverse of removal. Tightening of the new plugs should be done with a torque wrench, or in the absence of one, just dont arm wrestle the plug!
Now the car runs a bit better and has improved fuel economy.
