SOURCE: I need to remove the upper intake manifold plenum.

There are no fasteners inside the plenum, The electrical connection for the injectors is very tight due to a rubber ring gasket the seals the injector assembly to the plenum. Carefully push down on the electrical assmbly while prying up the plenum. You also may have to remove the thermostat and hose. I've done this 3 times on my ladies 96 Yukon.

I cannot post a picture here because that is copyrighted material. However, the torque sequence is always "start in the center and work your way out to both ends...pretty simple.

The torque specifications are different depending on which engine your Escape is equipped with.

How to change spark plugs

You will need a 12 mm wrench and socket, a 10 mm socket , an extension and the socket for your spark plugs, and an intake plenum gasket. Start by pulling the positive cable from your battery. Next pull the intake cover off the top of the motor. On the drivers side you will see 3 coil packs or "cops" ( coil on plugs) those have two 10mm bolts, one on each side. Remove those , pull the coil, unscrew your spark plug with your socket, and replace.
On huge passenger side you will have to remove the upper intake arch (plenum) to get to the remaining three plugs. Repeat process from the drivers side. !!!!replace your intake gasket when you remove the upper plenum or you will have a vacuum leak.

Do i have to take the intake off to change the spark plugs

You did not mention which engine you have, but YES, it is necessary to remove the upper intake plenum to replace the spark plugs on the rear bank of most Toyota V-6 Engines. This is why many tune-ups are as expensive as they are...The old days of getting a 6 Cyl tune-up for $59.99 are long gone...

You have a blown intake manifold gasket, a very common problem on these engines. Don't let anyone tell you it's the head gaskets. To do the intake, you have to remove the upper intake plenum, valve covers, coil bracket, and some brackets at the front of the engine. It is a big job but possible at home if you have a good tool set and some experience. Fel-pro sells a gasket set just for this job.
