    I think even more so when the SC has been lowered.

    I'd guess you could use sheet stock instead, but I'd try not to pin the plastics so they can move around a bit as needed.

    I think that piece contributes to the development of a low pressure area behind the radiator, allowing cooling air to flow through the radiator and not underneath. (Edit: As KMT just said.)

    You can run without it, but it will probably cool better with it.

    I think the material is called "masticated rubber".

    Does anyone have pictures of the actual factory wing nuts that were used with this?

    MP has a replacement that was advertised to help keep the engine cooler then the stock unit. Have had one in the box for years. Hoping to install it soon.....

    Think this is why the 89-93 got started as that is what their site says it fits. Link below.

    That's the external chin spoiler that goes outside the engine compartment, in front of the radiator's lower intake region on the lower back nose. The OP is asking about the skirt, that is after/below the radiator, basically inside the engine bay.

    I think I have one sitting around at home, but can't quite remember where. If I remember right, it looked just like this, but natural steel finish.

    Mine has little black threaded plastic caps. I'll try and get a picture tonight when I change the oil.

    Thanks Kurt....dag, those look pretty unique. Not your average butterfly nuts. Those are going to be tricky to source

    Ah, Kurt is right. That is the style of nut that came on my car as well.

    This got me wondering where to find such a thing. It took some digging, but I believe I have tracked them down. That looks to be a "Zip Twist" nut, style "JZ". I see references to a 3/16" size and a 1/4" size at the manufacturer's site. Auveco says they have them to fit 6mm studs (close to 1/4" anyway).

    Great find! I'm trying to source another one of those covers so I can fiddle with the installation. After I find one I'll order some of these zip twists and report back...it's probably going to be some time until I try this unless someone decides to try them first.

    Kurt...would you be able to take a picture of that wing nut with maybe a quarter coin next to it? Just so I can see the size in a different aspect ratio. I ordered what I thought were OEM (or very close to) nutz, but they seem very small to me! I'll snap a pic of them to share.

    Also, I bought one of these engine cover things and it came with the fasteners. Lo and behold, this cover came with a different plastic nut thing and does not use the metal one in your picture. I'll share a pic of it during the week. I get the impression that they may have switched over to the plastic one at some point. Not sure if it was a 94-95 thing or a 96+ thing.

    By the by...if anyone is looking to source the fasteners for the OTHER side of this cover...where it attaches to the body and not the metal tube, I was able to source them. Old part is on the right.
