how much horsepower/torque would a throttle body spacer add to my 1999 Pontiac

firebird V6? its a 1999 Pontiac firebird V6. just wondering if the throttle body spacer would help me out with horsepower/torque.

Barely anything, it's a waste of $$$.

Ask yourself this if it added power why didn't Pontiac do it? No performance gain worth mentioning if any at all. Might actually loose power.

Not as much as an LS swap would, V6 F-bodies are a waste of time honestly.
