Tomorrow I going to pull the spacer out. And see if it runs cooler.
I'm not sure it is teflon. But it looks and feels like it.
When I start the motor the intake runners are the same temperature as the head. And the bolts that hold the manifold on. There is no water passages in the intake so it should take more time to heat soak. And as it idles you would think the incoming air would cool the manifold somewhat.
Icing the intake picked the car up a solid tenth last year (when I had water a passage in it)
I cut the water passage off but the manifold seems hotter than last year.
