I found it on eBay for $40 with shipping, decided to give it a try. It lowers the underside of the front bumper by about an inch. So I think it might prevent some air from going under the car, and improve the aerodynamics.
I think it looks kind of cool anyway.
I need to reinstall the partial grill block. I removed it when I was having issues with overheating. Turns out I had a blown head gasket. Not sure if the grill block contributed to the blown head gasket or not...I will most likely install a less aggressive grill block.
