radiator cooler protection

If the guard sat up immediately next to the radiator (aka touching radiator), then I would say yes to obstruction. I am leaning toward negligible obstruction as sits of from radiator. My guess is there is a math formula for this.

It's not leaves but all the small holes that do not flow well. Air does not go at right angles through a hole but curves around the obstruction thus only going through the very center of the opening. Just one persons opinion!

I guess if you were driving in the fall and leaves were falling off the trees you could have a problem, but same effect would happen even if just a radiator too. We had them on the 1931 Cadillacs - they were standard equipment that year - They are sort of a whitewall glitz kind of thing and certainly look better on some cars verses others.

I completely agree Mike. In addition they distract from the really good looks of the front of the car.

I have always had the opinion that stone guards will restrict air flow through the radiator. Does anyone have another opinion? I have driven some miles and have never had a stone in a radiator. A broken windshield, now that's another matter!

I would like to know the answer to your question too (I use to know 10 years ago, but a lot has changed as to suppliers). Henry Yeska use to make, I think another fellow by the name of Burr Nurberg, and I think Brassworks bought out someones business.

Hello,

I want a protection for the radiator of my Auburn 6-66, for example shown in the picures. Does anybody know where I can buy or is it self-constructed?
