You will not see any gains with a throttle body spacer on a fuel injected engine or any horse power gains. From a common sense perspective (and common sense is not so common these days), if it were really that easy to add significant amounts of horsepower or fuel mileage gains, then these spacers would be stock equipment from the factory. Any Manufacture would add these for the amount of a few dollars for a piece of plastic installed between the throttle body and the intake if it would give them that competitive edge over the another manufacture. In older (long time ago) fuel injectioncarburetor models where fuel was sprayed directly at the throttle body and then mixed with the air immediately before being routed to the cylinders, it might have made some difference (not a whole hell of allot) but in today's injected engines were fuel is injected into the cylinder the chances that air getting to the cylinder would still be feeling the effects of a vortex by the time it got through the intake would not be seen. All these are good for is the fun of doing the install or the weight it can have holding down the instruction papers prior to its installation.


I love this quote from Richard Rowe "Once used by Aragorn, later King Elessar Telcontar, to defeat the forces of Sauron, throttle body spacers have been independently proven to create tornadoes in your engine, turn lead into gold, raise unicorns from the dead. Actually, they just add a bit of volume to an intake manifold's central plenum, but don't tell that to some of the people who market them for use on modern fuel-injected engines."
