Default Replacing spark plugs on 3.7L

I have about 96K on my 2011 3.7L and I'm getting ready to change the plugs. Left bank is easy, but it looks like the right side is PITA. Do I need to take the whole intake off? Does anyone have any tips and tricks how to get to that side. I searched the forum and YouTube, but didn't find anything. Thanks for the input.

I'll have a look tomorrow on mine and see if I can make a suggestion. Do you know what the spark plug gap is suppose to be for the 3.7?

Just the upper intake needs to be removed. All data says 1.5 to 2 hours.

At advance auto parts they said that the stock plugs are iridium, so I went with Autolite XP5364 iridium and they are pregaped, so im not sure what the gap should be.

Should be gapped at .051 to .055 in torque to 133 lb-in

I know nothing about spark plug gapping. Is there a big difference between .051 to .055? What is optimal? Just wondering because I want to check the gap on my plugs. I've heard they are not gapped properly from factory

Just checked the gap on all new pugs and it was .47-.50, so I adjusted them to about .52

Has anyone replace the plugs them self? I looked it and it seems like I got to take off everything from the top of the engine including the heater hoses and I guess, the top fuel line.
Can anyone tell me what only to take off and how will the intake manifold come off? Does the whole thing slide forward? I worked on several cars, but this is bull****. Thanks for help

I just looked and just the upper half has to come off. Mostly vacuum hose PVC brake booster and throttle body wiring and a brace. A lot of car need the upper intake removed for plug replacement. Once you take a real good look at it you will see there really isn't much to it.
