You mean one that can squirt more fuel? Sure, but they won't increase your engine's HP. The OE injectors are already able to provide more fuel but the engine computer tightly controls that in order to keep the air/fuel ratio where it needs to be. If you installed injectors that could flow more fuel, the computer would just shorten the pulse width to shorten how long the injector sprays fuel. The combination of the 02 sensors & PCM are highly effective at keeping a tight rein on how much fuel gets injected into the engine.
