Do I need the Air Intake Heater Boost Plug Adapter to install a Boost Gauge?Updated 2 hours ago
No, the Air Intake Heater Boost Plug Adapter is not required for installation. However, it can make the installation much easier by providing a convenient location to connect your Boost Gauge without making permanent modifications to your vehicle.
The adapter is specifically designed for 1999.5–2002 Ford Super Duty 7.3L Power Stroke and 2001–2004 6.6L GM Duramax applications. It allows you to obtain accurate boost readings without the need to drill and tap the intake manifold.
