1992 Trans Am

The original hose vs the NOS GM hose. The difference is that this NOS one (p/n 10055872) is longer, for earlier TPI cars that had the CC Vent Tube connection at the rear of the valve cover. The most important thing is that the curves are molded exactly the same and the throttle body side has a larger diameter than the end where the fitting connects the hose to the valve cover fits.
