this is not a racing device, this is for the daily
driver, one
that would need better throttle response,
drivability and fuel
economy. with our patented design we have
increased the air flow
at the intake manifold port 3-8%, thus more air
enters the engine
at low engine speed. the increased air volume is
detected by the
heated oygen sensor and readjusts the fuel mix to
a specified ratio.
more air in, more mid power, less foot pressure to
obtain 20-60hp
needed to keep a vehicle at speed. the less foot
pressure is
using less air, thus using less fuel with the same
power output.
yes the thickness of the spacer is increasing the
manifold plenum
volume, but its the throttle body spacer design
that allows the
more efficient air delivery to the intake port.
smooth bore spacers
do not promote this type of action and thats why
we say not all
throttle body spacers are the same.

On top of that all, honestly I was skeptical about them too
myself until I started selling them and customers came
back raving about them and their friends come back and ask
for them by name because of how much they like them.
So customer feedback has been overwhelming for the last
2 yrs on them.
