This is one of two brass colored diaphrams connected to the suction hood for an E21. The vacuum limiter is the one with the vacuum line and the mounting bracket. E12's have a limiter also but it's gray and is just above the valve cover near the fire wall.
The vacuum limiter does just what it says, it limits the amount of vacuum that builds up in the intake manifold. |
