Has anyone used/use one of these?(basically a spacer between your tb and manifold...i believe).
If so did you notice any difference?
Im thinking of making one of my own.

This came up a long time ago. Several people tested it and apparently it did nothing for our cars except made noise.

doesn't do anything on your car.. except possibly decrease power (as tested by.. I forgot who, he dynoed one, lost power).

it's designed for trottle body injected cars, not multiport injection cars.

Thanks.
Dodged a bullet there:nono

This is funny. I was just reading a dodge site where they contacted the manufacturer to find out why their car did not show any increase in HP or TQ on the dyno. the manufacturer stated that "it was not meant to increase any of those, and the improvements would be found in better mileage and throttle response"

btw. the 4litre cars did show a marginal improvement in power. the site attributed it to placement of the intake plenums.

just thought I would share.
