I have 90k miles on my 2011. It runs great but the mileage is down a little bit so I would like to replace the spark plugs. Does anyone know of any available videos that shows how to get to the passenger side bank of plugs? Drivers side is easy but the passenger side is totally covered by the air manifold.

I can't seem to find anything on removing this.


Thanks for any help.

Can anyone tell me if the intake manifold needs a new gasket if it's removed to change the plugs?

Yes the upper intake manifold has to come off, the gasket should be replaced also. If you are just replacing the spark plugs, I would suggest that you also replaced the spark plug boots also.

What engine is this that you need to pull the intake manifold to swap plugs ?

It's the 3.7L flex fuel engine.....2011 model.

When you say replace the boots, I assume you mean the coil plug that attaches to the plug itself? Do they have a history of going bad?

Boots and springs connect the COP to the spark plug. Not the electrical connector that plugs into the COP.
