The APR Universal Electronic Boost Gauge is a stand-alone unit designed to work in conjunction with a 52.4mm gauge pod. Available in multiple color combinations, the gauge reads up to 30 PSI under boost and down to 30 in.Hg in vacuum and includes an industry standard 12 month warranty. The high quality gauge needle sweeps with smooth and precise motion thanks to a microprocessor driven stepper motor that also self calibrates on startup. The gauge features an anti-fog lense, rubber seal to prevent light bleed and is LED back lit and dimmable through factory dimmer or an aftermarket LED light dimmer. The kit includes a 3 bar MAP sensor, universal harness, OEM butt splices, hose, clamps, zipties and universal mounting hardware to make integration into compatible gauge pods a snap!
