Mechanical boost gauges are straightforward devices that are incredibly easy to install. They operate in almost all vehicle types and are very reliable. Mechanical boost gauges measure the pressure directly, which is why they tend to be more accurate than digital ones. Because of the retro design, they are also suitable for old-fashioned vehicles. Most buyers find them budget-friendly.
Unlike mechanical boost gauges, these devices electronically monitor the applied boost and estimate the pressure, sending the estimated information to the display. For that reason, digital boost gauges are considered less accurate than their mechanical counterparts. However, they are more comfortable to operate and have a modern design to complement newer vehicle models.
One thing to keep in mind with digital boost gauges is the price and the installation. These devices are often quite expensive and require an electronic setup.
GlowShift was founded in 2004 and is located in West Berlin, N.J. The company produces all kinds of gauges, gauge accessories, and replacement parts. For over 15 years, GlowShift has offered many gauge series to meet the needs of all buyers on the market. The GlowShift Boost Gauge is our best overall pick.
Bosch is a German multinational company founded back in 1886 in Stuttgart, Germany. The little "Workshop for Precision Mechanics and Electrical Engineering" quickly evolved into a widely popular engineering and technology company. In 1906, Bosch established its presence in North America, and it is one of the first choices in the USA when it comes to auto parts, equipment, tools, and more. We find the Bosch Mechanical Boost Gauge the best budget-friendly option out there.
Boost Gauge Pricing
- Under $50: At this price point, you can get reliable mechanical boost gauges with an elegant design to compliment your vehicle. They only might lack some extra features for more user convenience.
- $60 and up: Digital boost gauges can turn out to be rather expensive because they work with electronic setups and offer features such as colorful LED displays. However, they make a good investment for those who want a modern and more comfortable design.
Boost Gauge Type
First and foremost, you'll want to decide on a particular boost gauge type. As mentioned above, there are two main types available on the market. The mechanical one measures the pressure directly and features an analog display. Digital ones have digital displays and monitor and estimate the pressure electronically.
We recommend choosing the type depending on your vehicle model and your personal preference. You want to make sure a device will work properly and efficiently and to pick the one that looks good in your vehicle. A boost gauge is an efficient device with a great capability to improve the vehicle’s interior and make it stand out from others.
To make sure a boost gauge will work in your vehicle, it's crucial to check its compatibility with a particular vehicle model. For example, a digital unit demands an electronic setup and won't work without it. A mechanical boost gauge works with almost all vehicle types, but we still recommend caution. The best would be to contact the seller and check each device's compatibility with your particular vehicle. That way, you can avoid mistakes and buy the best boost gauge for your needs.
- Design. You can also pick the overall design of the boost gauge so it complements your vehicle. These devices come in many colors and shapes. Some of them have elegant single-color displays, while others have an LED multiple-color system. You can pick the perfect one for your needs and also make sure you'll be able to read it easily during rides.
- Budget. Another thing to consider before the purchase is your budget. That will help you narrow down your choices and make a pick without overspending.
