AEM X-Series Boost Gauge Kit, -30 inHg to 35 psi - 30-0306

The AEM 30-0306 is a 52 mm X-Series digital gauge that measures boost and vacuum from -30 inHg to 35 psi (-1 to 2.5 bar). The kit includes a 3.5 bar brass manifold absolute pressure (MAP) sensor, a tee fitting and vacuum hose.

For turbo or supercharged builds up to 35 psi. To control boost as well as read it, see the Tru-BoostX gauge and boost controller.

Fitment and requirements

• Needs a manifold vacuum/boost source to tee into (tee, barb adapter and hose included)
• Needs switched 12V power, a ground, and a 52 mm (2-1/16 inch) gauge pod or panel hole
• No vehicle-specific harness; check clearance behind the pod for the gauge connectors

What it does

Frequently asked questions

Does the AEM 30-0306 come with the boost sensor?

Yes. The AEM 30-0306 kit includes a 3.5 bar brass MAP sensor, a tee fitting and vacuum hose.

I run more than 35 psi. What should I use?

The Tru-BoostX gauge and boost controller reads up to 80 psi.

Can I log the AEM 30-0306 with an HP Tuners MPVI4?

Yes, with extra hardware. Wire the gauge 0-5V analog output into the PROLINK+ cable (sold separately), which brings external 0-5V signals into VCM Scanner, and enter AEM's boost scaling from the instructions. See the HP Tuners MPVI4.
