Thank you all for your feedback; much appreciated... I'm very much relieved that we're discussing my bad choices more than the product; my poor choices can be changed...
Thank you very much JohnnyOhh for towing the line of reason; reason is always welcome around me. Not saying I'll always listen to it, I am very stubborn after all, but it's always welcome. And thank you SQ_Bronco for pointing out that I'm overestimating the fire risk these capacitors pose. I've never dealt with capacitors much and for some reason I was assuming they'd have a higher safety risk, like a Li-Ion battery, but that was just foolish on my part.
In defense of my foolishness, so-called Cold Air Intakes put their cone filter in pretty much the same location as I'd be putting the capacitor. The capacitor would sit at the bottom of that cavity behind the headlights, pretty much the lowest point in the engine bay. It's also on the opposite side from the exhaust manifold, so honestly, I wasn't overly concerned with the heat aspect of it. My biggest concern was water intrusion when I take 'er water skiing with the crappy drainage the country roads have around here.
If there's minimal fire risk from the capacitor itself, then I'll just put it in the cab... Is that pretty much the extent of the risk with these things? Nasty crap leaking out? That I can deal with...
