im just saying they are useless, leave those to domestics. there was a guy on h-t a few years ago when spacers was the new craze and he dyno tested a tb spacer and they didnt yield nada, infact he lost tq.

im just telling you they are worthless. a hondata intake manifold gasket is a similar mod that works in a similar part of the engine as the spacer but doesnt yield hp with one of the most misconceived tornado turbine, whirly twirly, air effects but with simple logic, keep the IM cooler, prevent heat soak, keep the air cooler, retain more hp.

theres a dyno spread on h-t with hondata IM gaskets yielding 6-10whp.
