Boost Gauges
Boost Gauges: read your manifold pressure so you can tune with confidence
A boost gauge shows what your turbo or supercharger is doing at the manifold, in real time. When you're running forced induction, boost gauges are the difference between guessing and knowing - you watch pressure build under load, confirm your wastegate or solenoid is holding target, and catch a boost leak or overboost before it costs you an engine. Vacuum/boost units also read manifold vacuum at idle and cruise, which is useful for diagnosing a rough-running motor. Fit one, plumb it to a manifold reference, and you finally have eyes on the number that matters most on a boosted build.
What we stock
This page lists 29 boost gauges across 7 brands. The current price range for what's in stock runs from $83 to $594 - that is where things stand today, not a locked-in promise. AutoMeter makes up the bulk of the range with 16 gauges in the sample, followed by Innovate Motorsports with 6, then Revel and Turbosmart with 2 each, plus single listings from Garrett, Go Fast Bits and Kuryakyn.
Concrete examples: the Innovate ECB-1 Boost/Ethanol Advanced Complete Gauge Kit sits at the top of the range, as does the Innovate SCG-1 solenoid boost controller and wideband gauge kit. In the middle, the AutoMeter Cobalt Digital 52.4mm Vacuum/Boost gauge pairs a digital face with vacuum reading. For clean digital OLED options there's the Revel VLS 52mm 30inHg-45PSI Digital OLED gauge and the Revel VLSII Boost 52mm gauge. The Kuryakyn Alley Cat Fuel & Battery gauge shows the range extends to matching gauges beyond boost alone.
How to choose
The main trade-off is analog versus digital and single-function versus kit. A straight 52mm boost or vacuum/boost gauge is the simplest install and the lowest cost. Digital OLED faces like the Revel units are easy to read at a glance and suit a modern dash. At the top end, the Innovate kits do more than display pressure - the SCG-1 adds solenoid boost control and a wideband, so you're buying a control and monitoring package, not just a gauge. Decide whether you want one number or a system, and pick your gauge size to match your pod or dash location.
What else you'll want
Wiring a gauge in usually means running power and ground, so browse Electrical Accessories. If you're building out the cabin at the same time, look at Racing Seats, Shift Knobs and Quick Release Levers. All of these sit under the broader Interior section.
Fitment and ordering
None of these listings carry vehicle-specific fitment data, so match the gauge by size, function and your reference source rather than by make - though some products name applications like Ford and Dodge in their titles. Every order ships free, and Affirm and Katapult financing is available. If you're unsure which gauge fits your build, use the fitment calculator or reach our team through contact us for fitment help by phone.
