2009 Subaru Forester 2.5L: Replacing the spark plugs and spark plug wires

In this video, I replaced the spark plug plugs and spark plug wires on a Subaru Forester with the 2.5L naturally-aspirated (non-turbo) engine. I recommend that the spark plugs be replaced at 50k mile intervals. This vehicle developed a misfire due to running the spark plugs for nearly 115k miles. Unfortunately, the spark plug wire boot for cylinder #1 was damaged due to spark energy burning a hole through it, so I went ahead and replaced the entire set of spark plug wires.

This process should be similar on 2009-2013 Foresters with the naturally-aspirated 2.5L engine. Also other Subaru models with the 2.5L.
