Want to keep an eye on your turbo's health and performance? This Hewitt boost gauge is a simple and effective tool. It's a mechanical gauge that reads from 0 to 50 PSI of positive pressure (boost), with a 270-degree sweep needle for easy reading. The 2-inch dial has white numbers on a black face, a red pointer, and a black bezel – it lights up with red LED illumination so you can see it at night. The kit comes with everything you need: the gauge itself, an 8-foot long pressure hose, and all the necessary fittings to tap into a boost source (like the intake manifold). Monitoring boost is great for diagnosing turbo problems (like leaks or a failing wastegate) and for making sure your tune is running safely. It's a universal kit, so it can work on most turbocharged cars, trucks, or diesel engines. Easy to install and gives you real-time info about what your engine is doing.
