I didn't video or photo my install but suffice to say it's pretty straight forward. The two Torx screws that are captive on the coil covers are the only mechanical attachment to the engine. A couple of hoses/tubes need to be disconnected to facilitate the cover removal/replacement. Drivers side; PCV tube/hose needs to be disconnected, by simply depressing the grey bar near the bottom of the female fitting (just pull and position off to the side). I also disconnected the braided stainless fuel line to give better access/clearance to slip the covers on/off without scratching them. Most parts houses sell the little plastic "keys" to slip in from behind the fuel line fitting to disengage the fingers to take the coupling apart (easy). Passenger side; The primary issue is the PVC fitting in the center of the cover. The male (plastic) fitting (the part with the hose attached, that you can wiggle) has two "barbed tangs" that go into the metal (female) port. If you are rough/heavy handed, with the plastic fittings, you will likely break off one or the other "tang". I ended up making myself a little metal "tool" from sheet metal flashing that I shaped in a curve that I could slip down into the gap between the male and female fitting and flex the forward (towards the front of the car) tang enough to disengage with a slightly firm pull upward. The replacement fittings (I understand) are not that expensive, so if you break a tang you can get a new one. If you break a tang, you need to "fish" the broken piece out. I also removed the small 10mm nut and bolt that secures the coolant recovery tank to shift it away from the cover, but mostly to install the new custom one and not risk scratching the paint. The whole job took me about an hour including; some chin rubbing, drink a frosty cold adult beverage, use some detail spray to remove the smudges from my fenders. (lol) Hope this helps.

What is the trick to disconnecting the manifold absolute pressure sensor connector? This must be removed in order to remove the intake manifold cover. Doesn't seem to pull right off.

Thanks...

You need to keep the red collar pressed against the manifold body while pulling the fitting out. Then it comes out easily! The red collar is the lock. It comes out with the fitting, getting it to release is the trick. Otherwise just pulling on the fitting makes it lock harder... I used a plastic trim tool with a forked end to hold the collar against the manifold. Very limited space to work. Good news is that pushing it back in is easy!

I dont see a red collar.
