Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
Is it necessary to remove the upper intake manifold to replace the spark plugs? If so, how do you do this and will a gasket need to be relaced?

The ALLDATA manual I referred to did not appear to suggest removal of the upper intake is required.
