|What does that have to do with manifolds?

|I have my A2 intake manifold ceramic coated in that polished look stuff. It looks ok except that the ceramic coating does still show any little imperfections in the surface of the manifold. If you were to totally smooth your VR manifold I bet it would look pretty good, but it isnt quite a mirror finish. Mine's kind of wavy.|
The A2 manifolds seem to have a rougher cast than the VR ones so if you smoothed all the lines it'd look good. I dont know how much it'd benefit the motor, but it certainly cant hurt.
I paid somewhere arount $250 to have both manifolds and my down pipe coated.

|Now here's what I can tell you about the reduction in heat. (Not super scientific, but makes the point)|
The above picture was take the morning of the Evolution Sports/ waterwagens Cruise to Leavenworth, WA. This drive started @ Evolution Sports in Everett (elevation 150ft) and the first stop was the top of Stevens Pass (elevation 4061ft) which is about 60 miles. In the group that I was driving with, there was an another AAA with no EvoHeatShield and No Coatings, that had basically driven the same manners I had. After getting to the pass and shutting down for about 5-10 min. someone says let's see if the manifold spacer and coating really do anything. So, we walk over to the factory manifold car and place our hand on the raw aluminum where the sound cover (this piece that says VR6 DOHC) normally is and you get that feeling that you just grabbed a hot pot off the stove. You all know what it feels like, where you pull your had away and then you feel the burn, like your brain can tell your had to move but hasn't told it why
Again this was a very basic test, but it tells the story.
