Phenolic intake manifold spacers

[Ken]

Hey folks,

I just found this:

Some info on the heat insulating spacers that were discussed a few days back.

On the author's Mazda V6, he reports the following results:

"The intake ran 30 degrees F (17 degrees C) cooler at cruise and at least 50 degrees F (28 degrees C) cooler at idle;
According to my dyno plots, I gained up to 7 horsepower and 11 ft-lbs of torque over the major portion of the power curve.
My best time at the track was ~0.1 seconds quicker and ~1 mph faster."

Later,

Ken
