Cowl air intakes - How noisy are they?

I'm considering a cowl air intake for my XJ, but don't want increased noise in passenger compartment.

How much increased noise would there be in pasenger compartment from a cowl air intake?

I've had one for a few years in my TJ and really don't think it adds any noise. I've wondered if it depends how close you get it to your HVAC intake. I've got a windstar box under the hood right at the firewall with just the stub of the intake in the cowl. Other designs though where more tubing (and in some cases filters) under the hood.

Do you have any pics of it? I'd like to see it. I always enjoy seeing people's cowl intakes.

It's definitely noticeable in an XJ. You have to do it on the passenger side near the HVAC because everything for the wipers is on the drivers side in the cowl.

HVAC is an abbreviation for what?

No photos, but very similar to this:

I did use a PVC elbow to make the bend which is a little different.
