I was impressed by how much is included in the kit. You get everything from the nylon line and T-fitting to the bulb and socket assembly. The traditional incandescent lighting provides a classic glow around the dial perimeter, and the inclusion of red and green bulb covers allows you to customize the look. Because it relies on mechanical movements rather than sensors, you can trust its durability even when the engine bay gets punishingly hot or vibrates heavily during high-performance driving.

I love how it combines a traditional analog pyrometer for EGT with modern digital displays for boost and temperature, giving you a comprehensive view of your engine's health without cluttering the dash. The gray single pillar pod is a standout feature here, as it's factory color-matched and made from UV-protected ABS plastic to look like it belongs in your 1999-2002 Ford.

The anodized metal finish catches the light immediately, signaling a level of durability that goes far beyond cheap plastic alternatives. This 2-inch gauge is built from high-strength metal, making it resistant to dust, scratches, and even corrosion.

It is a reliable, easy-to-operate piece of kit that adds a professional, high-tech characteristic to any car's interior dashboard.

You aren't just getting a 60 PSI boost gauge, a 1500°F EGT pyrometer, and a transmission temperature gauge. You're getting a complete cockpit overhaul. The Black 7 Color Series is a standout, allowing you to toggle through seven solid colors or two cycling modes to match your interior vibe.
