As in, throttle body spacer? If that's what you are looking at, don't bother. They do absolutely nothing on a port injected engine.
TB spacers were originally designed for carbed engines, or throttle body injected engines, where you had "wet flow" thru the intake. I.E. fuel AND air. The idea was the turbulence induced by the spacer would keep the fuel in suspension, thus, making the engine more efficient. In a port injected engine, there is no fuel in the air stream, until you get VERY near the intake valve, thus, the turbulence induced by the spacer only serves to disrupt airflow, thus making the engine LESS efficient.
