I have sitting on my table a stainless steel air filter from Evolve. They threw that one in along with the air filter that was used on the blue car. Don mentioned that he didn't recommend the air filter for daily use, because it's harder to clean. It just looks so darn cool though. Why would it be difficult to clean I wonder?<p>I'll take pictures when I'm not feeling lazy.<p>Basically, it looks like this one, except made of stainless steel:<p><IMG SRC="http://www.evolvecars.com/albums/album27/CIMG1778.sized.jpg" BORDER="0"> <p>Oh by the way, I have that turbo pipe too. I'm debating whether or not to install it.
