The AEM 3.5bar MAP sensor is the perfect upgrade for those who are looking for more boost. Most MAP sensors cannot register (safely) over 11psi and after going past that point you will need to upgrade so that your engine management can correctly figure out where the engine is on the map and add the correct amount of fuel/timing.

Note: This is MAP sensor comes with connector and is good for reading upto ~50psi of boost. Has 1/8" NPT fitting on end for installation.
