So what is the latest verdict on phenolic spacers?

Yay or nay?

Mine are still good (2 cars running them)

I have only run them to run in the motor. So only 1200kms approx of engine running time

I am just trying to figure out if it is a worth while investment or not? Seems great in theroy but I have no real worl data /ubbthreads/images/graemlins/confused.gif

My bet is that the air charge is only a little cooler, but it would be nice to have a gasket that will be able to be reused several times.

It can definitely only help and they aren't that expensive.

You should be aware that a spacer will increase the effective runner length which will lower the rpm resonance point. It may be a minuscule effect but it will change the power-band slightly.
