I've been wondering about this commercial Tornado thingy...
Personally I first saw it in Taiwan (where lot of stuff do
not work as advertised).  In EFI systems with throttle bodies,
won't what ever vortex effect the Tornado generate just hit
the throttle plate and lose effectiveness?  What about after
it divides in the plenum/runners?

Most people on rec.autos.tech think it bogus too...  What
do the people here think?
