Guide overview

Before you begin

Spark plugs are a crucial heart of any engine. If your car seems like it is running rough or misfiring, chances are your spark plugs are wearing out and need replaced. Spark plugs combust vaporized gasoline in the engine, which is the fundamental of any engine. If your spark plugs get old and wear out, they will not spark and that cylinder of the engine will not fire. Our guide will be showing how to replace the spark plugs on a 2011 Ford Mustang with the 3.7L V6 engine. This guide is applicable to other V6 Mustang’s from 2010-2014. While this is a routinely simple procedure, make sure to keep all the parts removed from the engine clean and away from debris.
