Grizzly snorkel

So who's got some pics of their home made snorkels? Or rather, who HAS home made snorkels? I've been thinking of running one myself, not that I'll ever drown my grizz to that depth, more to relocate the air inlet to a more cool-air environment. In fact, today was the deepest I've had it... right up to the bottom of the fuel tank. But as I was in water of this depth, it started running aweful, (I can only assume from taking in alot of steam) and thought this would remidy the problem. It was probably the warmest weather I've had it in, yet (85*). Any thoughts? Thanx.
