2004 Mazda Mazda6 Question: Spark plug replacement



6 owner, 3.0L V6, Syracuse, NY, August 24, 2009, 10:49

What needs to be removed and in what order to access the back three spark plugs for replacement? It is very congested and I thought there must be a standard proceedure to get to them?

    There is no standard procedure to replacing spark plugs. Many times if unable to reach spark plugs from the bottom, removal of upper intake manifold is required to gain access to spark plug replacement. It would be best to purchase a Manual for your vehicle from your local parts store and see what it would take to remove upper intake manifold.
