It took me two hours to remove the upper and lower cowls. That's a far as I got because I could not remove a 4mm screw holding a belt clamp on the air intake-throttle body connection. That's right. A belt clamp ruined the entire job. First time in my life I had to abandon a job like this, but I reassembled everything and went home.
Got to figure out a plan. Maybe hacksaw off the belt clamp.
Four 12mm bolts that hold the throttle body on. Two Brackets on the back side of the throttle body hold the four 12mm bolts. (Two bolts in each bracket) Two 10mm bolts sitting right behind the throttle body, and a litle bit further down (If you are looking at the car from the front, lean your head all the way forward (given the cowls are off LOL) and look directly behind the throttle body. Cant miss them! One 12mm bolt. Look at throttle body and its the only 12mm bolt that faces the same way as the four bolts above. Five 12mm bolts holding the intake manifold to the plenum. (Stand facing the front of the car, look for '().()'().()' pattern. (lol) Two 10mm bolts holding the airbox in. One on high left side, one on low right side. (Easier removed if battery is taken out first) Seven 10mm bolts holding the wiper motor/cowl assembly on. (Sorry, taking out of jars is too loud..kids are asleep and wife is getting pissed lmao) Two 14mm bolts holding wiper blades on. Two nut covers (lol)
Starting from the bottom its in order of how I did it. Hope this helps. No 4mm bolt needed.
I think he's referring to the hose clamp on the throttle body. That does not really need to be removed. The entire assembly from the upper intake all the way to the air box lid can be removed as one piece.
If you want to remove the intake tube from the throttle body, a small phillips head screw driver will also work.
The less things you break apart, the better. I pull off then entire intake, throttle body, intake tube, air box lid as one piece.
Those are the 4 bolts and two retainers that mount the throttle body to the upper intake. Once again, those do not need to be removed. No reason to separate the throttle body from the intake. Remove it all as one piece.
I've done valve adjustments on our GD and two GE's.

This is my first time and i was going off of a YouTube video that most people use. Good tip for next time.
Could you answer a quick question..
Is it okay if I stop at the valve cover and continue the job in the morning? Maybe a dumb question but just making sure.

Explain, please. The thing that sits on top of the valve cover is called the plenum, right? The plenum is connected to the throttle body, which in turn is connected to the air intake (moving left to right).
Chuck, if you got everything off the engine down to the valve cover, then you are good to go. Tomorrow, you're going to remove the valve cover and adjust the valves. Then, reassemble and you're done.
Awesome, as soon as my bent feeler gauges get in I will definitely finish. Is it okay to have all four spark plugs and all four boots out of the vehicle at the same time?
I just did the valve adjustment on our new to us 2013 Fit with 72k and I didn't have any problems getting that clamp off. I must say however that I had an awful time getting all of the stupid plastic zip tie clips and other clips loose. Those little buggers are a huge pain. I spent 18 years without a garage and having one now for the last few years is wonderful. I can rip apart whatever I need to, close the garage door, and just continue the next day. FYI I am a definite proponent of the go/no-go method of setting valves. For instance if on the exhaust valves.010 slides easily but .013 won't go in, I know I'm good to go. Oddly I found all of my intake valves perfect but all of the exhaust valves too tight.

If you unclip the airbox lid, unbolt the upper intake plenum from the lower intake, and disconnect all of the coolant, egr, vacuum, and electrical connectors, you can then remove the upper intake plenum, throttle body, intake hose, and airbox lid as one complete piece.

That has been true for all Fit's I have adjusted at lower miles and it's an important thing to note. Tight valves do not make extra noise, but will cause the exhaust valves to burn up over time. Many Honda dealers and owners think you can judge the need for valve adjustment based on noise, but tight valves are silent.

I like the sound of that, GAFIT. I just have to figure out which bolts to remove.
Moving left to right, you have the plenum, the throttle body, and the upper air box (which looks like two chambers). I am assuming that the lower air box is the one with the disposable air filter in it.
This is not clear to me ---> "unbolt the upper intake plenum from the lower intake".
Sorry to sound even more stupid than I am, but perhaps you could further elucidate. Thanks.

Our intakes are two parts. Plastic plenum with aluminum runners. Some mistakenly unbolt the runners from the head, but there's no need. Just unbolt the plastic plenum from the runners and leave the runners in place.
If you have to remove the intake tube from the throttle body to access bolts, that's not a big deal. Just don't remove the throttle body from the intake. Serves no purpose and creates a possible leak point. I have done 4 valve adjustments on ours and even replaced the camshaft with a performance cam. No gaskets needed still. Just two small dabs of grey gasket maker each time.
The bolt pictures below from Chuck should be VERY helpful. Description of locations are great also. Just skip unbolting the throttle body part.
