Remove are label spark plugs from the spark plug only and remove spark plug and install new plug finger tight first then snug with a spark plug socket and reinstall wire and move on to the next one

Technically, the throttle body, and the upper intake manifold, called the "plenum".

I got by just disconnecting the plenum and propping it up enough to get the spark plugs in, because i didn't want to have to buy a throttle body gasket. If you know what you are doing, expect this to take about 30-45 minutes :)
