Are you in need of a way to access the pressurized intake air system to install a boost gauge in your '98.5-'24 Dodge Cummins Turbo Diesel?
If you made a mistake and bought your gauges elsewhere, you're still in luck. This adapter has a hole drilled through it that allows you to remove one of the intake manifold bolts that affixes the air intake to the cylinder head. Remove the bolt, replace it with Geno's Boost Adapter, and you now have access to pressurized air.
