I've seen this done before in person, but I always wondered if spraying water on a warmed engine would crack or warp hot engine parts like headers etc.
hmm i really cant tell cause of the pics so im not dissing your method just cant see enough to say ay or nay, your "dirty" engine bay is cleaner than mine
looks cleaner, but pics suck lol so cant tell much of the difference. Mine isnt too dirty at all, but its driving me nuts I usually clean my engine every 1st weekend of spring and 1st weekend of summer, but I have so many wires that are just everywhere right now I dont want to spray them until I redo heads and secure them properly.

I have sprayed my engine bay plenty of times as well and have a few things that I would advise.
1. Dont spray too much water at your spark plug wires, one time I did and some water got into the spark plug channel and the car started missing and sputtering until I figured it out and took an air hose to the channel to disperse all water.
2. Dont spray near any Aftermarket Car Audio Fuses or Circuit Breakers. I did one time and my circuit breaker wasnt waterproof, and it fried. Had to buy a new one. It sucked, LOL!
3. I would just take the precaution like I do to protect your cone filter. If you're using a factory airbox your fine, dont worry about it. But what I do that easy is as pie with my cone filter is:
Get a plastic grocery bag, cover the filter, then tie a knot at the MAF Adapter. Its pretty much safe at that point if you tie a good knot, never had an issue from there.
4. Watch out for any bare wires that may be exposed from loose wire harness looms. I took a car I had one time to a Car Wash for them to do my engine bay, they sprayed my engine bay and a wire got wet that was linked to my brake system which caused my emergency brake light to stay on for damn near 3 months. Had me pissed as ever, but it finally went away after I changed the master cylinder resevoir which had an electrical plug to it.
So moral of the story, DO be mindful and careful of what your spraying, bcz some of your wires or wire looms may be old and deteriorating, and or anything else eletrical, which can leave the opportunity to get something wet that will short out.
Stick with the concentrating most of water at the block, water and coolant resevoirs, headers, intake piping, firewall, but simply rinse off everything else eletrical with due regard.
At the shop I used to work at they had a pressure washer. So what they taught me to do was spray the engine bay down completely with purple cleaner soak it and then turn the car on and use the pressure wash to clean everything off and of course use air blower and blow out all the left over water.
I actually performed this prior to MOD to get my bay nice and clean . I actually just used my garden hose with a pressure nozzle and it worked just fine but keep in mind, you want to minimize the amount of oil runoff going to the storm drains. I did this because I cleaned the bay at a station with water recycling about a month prior, so most of the oil was already off. I covered the battery and my cone filter, then sprayed everything down with the tire foam and scrubbed whatever I needed to with an old tooth brush. Then I rinsed off with the garden hose, wiped as much water off as I could, then went for a nice drive to dry things off. Once I was back and the bay was cooled down, I used to Armorall plastic/vinyl dressup to get all the hoses and plastic looking fresh. Now the bay looks great :)
In the original post of DOHCstunr says tire SHINE aerosol, but I imagine he meant tire foam since he talks about snow looking foam, and many of you say tire foam, I think I'm going to try it but with my garden hose, Im gonna cover the alternator, the ccfl ballasts and the amp fuse, or is it safe to spray the alternator, since DOHC doesn't say anything.

I left my alternator uncovered. I wouldn't go soaking it, but I think it's okay to leave it uncovered. If you want to be safe though, you could just easily put a plastic bag over it. Also, if you use the garden hose, try not to get to thick of stream going, if that makes any sense.. haha just try to minimize soaking I guess
I work at a car wash and I tried this after work one day. My engine bay was clean and my intake was covered. When I started my car my drive worked for about 25 feet then stopped working. Reverse worked fine. After about an hour my drive would work intermittently and on the way home i had to stop multiple times to restart my car because that seemed to help drive kick in. Engine code was thrown during this i ran the code and it came up as over 11 circuit faults. Car dried over night and was fine the next day
hmmm sounds like you might have some wires exposed? either that or too much water gathered in one spot? I would make sure your wiring isn't chewed up though
I'll do this later tonight and get pix..Mine is ULTRA dirty
