I found a good hose at a junkyard. But do I need it? I put some screening wire around the opening and the clamp to keep the squirrels out. I'm hoping to gain at least 20Hp like all the K&N people claim. :stupid:

Site, the '75 I owned in my youth didn't have the snorkel, and it ran fine. My '78 has the snorkel. I'm certain it must have some sort of purpose, but it escapes me what it might be.

My 11/75 - 76 280Z does not have the snorkel.

The snorkel goes back to the engine bay. Could it be to prevent water satuating the filter when driving in a down pour or close behind another vehicle in rainy weather. The efficiency of a filter will reduce considerably when wet. That corner of the engine bay might be the dryest place they could find.

The idea would have been to get a cold air intake into the engine.

The thing is, olzed, the air would be cooler in front of the radiator than behind it.

Having once lived in a pretty dusty area, I would have guessed air from the engine compartment might carry a bit less dust than air from the front-side of the radiator, particularly if it had to circle back.

These snorkels extend down close to the road in some more recent models of cars. There have been cases in which engines would suck up massive amounts of water when driving through puddles. The water would then hydrolock the engine. Because the engine would be spinning at a good clip, naturally something would bust -- a piston rod, the crank shaft, or whatever. At least ours draw in air from up high.

I will buy a pin wheel at the Dollar Store and show you all how much air it's pulling at idle. I am amazed. Plus I have an extra opening now as big as a baseball to let air in the engine bay.
