I have a pan that runs from the radiator to the front of the frame to stop debris and water from coming into the engine comartment. Is there advantages or disadvantages to using this on a 240z?

This rare item was stock on the 240 but discarded quite often. I'm told it is good for helping air flow through the radiator.

You named the advantages in your post plus the one that kurtwwalters mentioned and I can't think of any disadvantages. If you have it on your car, I would keep it.

I didn't realize the pan was stock on all cars. Somehow I thought it was an optional item. I've never even seen one installed so I suppose a whole bunch of them got discarded.

If anyone is interested I have some available. Most for 280's but one for a 240.

I have one on my '73 and I did notice that it did help some at higher speeds to lessen the light feeling in the front end. I ran with out it for a long time as it was bent up and grungy , the PO had it in a box when I bought the Z . When I cleaned it up and installed it I did feel the difference , not a great difference but it helps. Recently I read that it was found that the air pressure under the front of the car is less when one of these pans is installed. So I guess I waZent dreaming. Gary
