WTB: Smooth Air Bellow
 

Just like the title says. WTB smooth air bellow. Trying to clean up engine bay.

Here's something you might look into I went to my local hardware store and found something that worked pretty good and much cheaper than SLP. It is a sewege pipe coupler it's black made of rubber and they come in different size's. I got 3''x3'' but I recomend..if they make this size 3.5''x3.5'' a 4''x4'' may work it look a little to big to me but I didn't try it. In stead of paying 60+ for one I paid under 6 bucks but just something I did maybe it will work for you too. Oh yeah don't look to bad either.

I checked those out and I thought they seemed very heavy. Maybe it was just me. I may consider it again. I know there were a few cracked lids with that mod.
