Velossa Tech definitely drops the temp

There was definitely a noticeable drop in oil temp while moving (at least 15°). Didn't realize how bad the stock ducts were. Drove it about 25 miles through pretty decent rain and cars kicking up water this morning. There were droplets of water, but nothing significant enough to do any damage. Would recommend.

But if you have a 3d printer, you can probably just print it and then epoxy coat it.
