4" OD Tubing Ideas

Looking for a simple and cost effective way to plumb my air cleaner to the TB. I want to move the air cleaner to the area just in front of the coolant tank. Thinking light weight, thin walled tubing, maybe stainless or aluminum (maybe even carbon fiber ) I've checked out *Bay and C list already.
Any ideas on a supplier?

I bought an intake for another car from a diesel truck shop, the 3" down pipe. worked good but might be heavier than you are thinking

Aluminum Tubing 4 Inch o.d., .065" wall thickness,
Price is per length of piece: one foot=$17;
2-feet=$27; 3-feet=$37; 4-feet=$47.

They also have the 45* & 90* rubber boots, clamps, etc.

These guys were good and reasonable [You must be registered and logged in to see this link.] Pep Boys and other auto part stores sell the Spectre line of intakes, including individual pipes and elbows, etc.

I'm in the process of re-working my intake too.

I think 4" is a little overkill for the intake--not to mention difficult to fit under the hood, which is really the only reason i even mention it. Even if you went to a 90mm TB, 90mm = 3.54" dia. (minus crossbar and blade = ~3.5").

Anyways, 3.5" tubing is really common on ebay in any flavor. If your headlights are still stock, i just ordered an RU-3130 air filter that should fit perfectly in front of the coolant reservoir....i'll report back on that when UPS delivers it tomorrow

The biggest reason i went with 3.5" was because you can't really fit a 4"x4" 90* rubber boot on the TB without removing the hood latch. Then the 3.5" tubing is cutting it close going between the p/s pulley and the headlight bar.

A final option i had considered was filling a garbage bag with expanding foam, laying it where the air intake was going to go, shutting the hood, then whittling down the expanding foam into the shape i wanted and laying some fiberglass over it. Would be a cheap and easy way to end up with a completely custom intake that uses every inch of space under the hood for airflow.

Porch...its a track car...its all over kill!
I've have a cam, LS6 intake, and of course the headers with a very open 3" muffler. BTW, the hood latch is long gone too.

Ah, if you've got no hood latch then you might as well go hog-wild!
I've got about 1' of 4" aluminized steel tubing, but i'm not quite sure if i'm going to need it or not. If you're not in a hurry i'll let you know...
