2009 Mazda 6 - 4 cylinder spark plug replacement ( and coils ) how to

Reasonably detailed description how to change the spark plugs and coils of a 2009, 2nd generation, Mazda 6, 4 cylinder. Correction 1) Do not use thread anti-seize - http://www.jagrepair.com/images/AutoR... Correction 2) Di-electric grease should not touch the metal, conductor parts of the plug. Only the white, ceramic portion of the plug.
