Has anyone heard of these for the SR20DE? I'm getting one for my S2000, and if it works out, my friend will get one for his Pulsar.

I guess nobody has heard of these. They claim 5-9% HP gain. I know of someone who got 12HP from an engine that normally puts out 200HP, so that sounds about what the manufacturers claim.

Sunder,

a lot of people have heard of this. Their claims are legitimate!

However, in most SR20DEs, the intake manifold and the TB are actually HEATED by coolant lines that pass through them in order to help in freezing situations and melt the sludge that goes in there from the EGR cirquit.

Unless your Pulsar friend modifies the intake and TB by rerouting the coolant lines so the do not pass through them, the phenolic manifold spacer will not do anything at all.
