Description
Product Overview
The Auto Meter 3607 Sport‑Comp II is a 2‑1/16″ mechanical boost and vacuum gauge designed for performance‑oriented street and race vehicles. Housed in a painted plastic shell, the gauge combines lightweight durability with resistance to corrosion and heat. A modern white LED shines through the dial, delivering crystal‑clear visibility even in low‑light conditions. The gauge reads up to 30 in. Hg (20 PSI) for boost and provides a precise vacuum scale, making it a versatile tool for turbocharged, supercharged, and naturally aspirated engines. Key specifications include a 9.6‑ounce weight, LED bulb type, and a fully mechanical movement that eliminates the need for any electrical wiring.
Usage
Designed for both street enthusiasts and professional racers, the 3607 gauge excels in environments where reliability and readability are paramount. Whether you are monitoring boost pressure on a weekend track day, checking vacuum levels during engine tuning, or simply keeping an eye on your daily driver’s performance, this gauge delivers consistent data. Its mechanical operation means it functions independently of the vehicle’s electrical system, reducing potential failure points in harsh racing conditions. Installation is straightforward: the kit includes a 1/8″ nylon line, T‑fitting, vacuum fitting, compression fittings, and all necessary mounting hardware, allowing you to mount the gauge on the dash, bulkhead, or a custom bracket.
