Description This external MAP sensor adapter allows you to install a 2G OEM MAP sensor when using a 1G intake manifold or any other aftermarket intake manifold that doesn’t allow for an OEM sensor. The MAP sensor is bolted to the back side, a vacuum line is then ran from the hose barbed side and tee’d into a pressurized source on your current intake manifold. (Vacuum hose and “T” fitting NOT included)
