The only way to show for certain whether these spacers are actually doing
what you think they are is to put a thermocouple (or other comparable
instrument) out into the airstream in the intake (right at the manifold
gasket) and measure air temperature under the same ambient conditions, with
and without the spacer. And under all the same other conditions, like hood
down, etc. At any reasonable engine speed, there are tens of liters per
second moving through EACH intake passage; it's hard to imagine that this
amount of air could be heated to any degree by the intake manifold.
It's possible that this mod is doing something other than what you think it
is. It'd take a much smarter guy than me (automotive-wise, anyways) to
figure it out. I'd also want to see a thermodynamic explanation rather than
hand-waving. Unfortunately I bagged thermo in favor of statics/dynamics.
And I'm kicking myself right now.

Subject: SML: New Mod: Phenolic Spacers
I have been talking to a member of the Probe list who developed Phenolic
Spacers. It is a spacer that lifts the intake manifold away from the heat
of
the block. Anyway I am a veterinarian. This is the site address and below
that is his address to reach him if you are interested. He has given
interest
to making a spacer for the sr20 but did not think there would be much
interest for the ga16. I have no way of telling you how accurate the dyno's
are. I will tell you that there are 100's of members on the probe list that
have bought this mod for their car. Anyway look at the site and make a
decision.

This was his letter to me.
Marcus,
We have considered Nissan applications, but have leaned more toward the
SR20DE with it's greater performance potential. However, if there is
demand, anything is possible.
Thank you,

Maybe we can get a cheap performance mod out of this.
Marcus
