Thickness
Length of replacement bolts to match increased thicknesses
Which exact grade of phenolic to use
Any comments, suggestions, discussion before I get too far down the rabbit hole?

When I looked into getting these made I did a bit of research, and altough I called GrimmSpeed the person I talked to didn't know the grade of the phenolic material. However they asked for my number and email so they could get back to me.
About 2 weeks later I got an email stating that they use Phenolic G10 GRE (Glass Reinforced epoxy). "G10 phenolic is mechanically stronger and provides the best in thermal transfer resistance translating into lower temps and more power."
I looked into it and this stuff can maintain a safe environment up to 500*F, can handle race fuels, E85 and methanol.
The two thicknesses Grimmspeed carries are 3mm = .118 inches & 8mm =.314 inches. Obviously thicker means better cooling and greater volume of air in the intake manifold.
Just like svxfiles mentioned below, the Outlaw Engineering ones were
.333 inches = 8.4mm. Cooling should be about 20-40*F depending on ambient temps.
As to the "Length of replacement bolts to match increased thickness" question. The
NEW bolts need to be 5mm longer than the stock ones.
Also, the cost for Outlaw Engineering spacers was $105 and that included the
intake manifold & throttle body spacers, shipping, gaskets, hardware and
stickers for 20+ AWHP
. Obviously, it wasn't enough since the company flopped.
I think somewhere around $115-$130 shipped would be reasonable for the intake manifold and throttle body spacers!
You have a happy customer here (SVX oil cap) and can't wait to do business again (Spacers).
