The ID725 Injector offers unmatched linearity in fuel flow even at extremely low pulse widths (ie: idle) for the best possible idle quality and stability while still providing enough fuel volume for any all-motor setup or mildly boosted engine. The ID725 injector offers better fuel spray and control at idle than even the stock Honda injector. This is considered the best injector money can buy for any engine under 400 wheel horsepower.
