How do you change spark plugs for 2000 kia sephia?
For the two in the middle, you need to first unbolt and remove the insulated boxes that cover the spark plug holes (you can unplug the white connectors but make sure you plug them back in when you are done). Then all you have to do is do the same thing you did with the two outer ones to replace the plugs. Perform this one plug at a time, and make sure you cover the holes with a cloth or paper towel if you leave them open for any period of time. When you finish, make sure all the wires are connected, then reconnect the battery.
