My buddy put those on his 93 Probe GT. Phenolic spacers or whatever they're called. They were a complete bitch to install, since they were for the intake manifold and throttle body. Saw maybe .4 hp increase on the dyno, but we think that was just because it was a little colder. I wouldn't waste my time/money on them.
