2017-2023 L5P INTAKE HORN

Why run an aftermarket intake air horn?

The factory intake air horn runs a surge tolerance area between map outflow area and the surge ring of 2.8mm. When the trucks are turned up to higher power levels the design of the turbo requires more map outflow into the surge ring area. We increase this tolerace area to 3.7mm to keep the pressure gradients across the turbo in check. This is not a tunable thing on MAP outflow, it is part of the turbo compressor cover design.

The surge ring built into this intake horn will work with the stock turbo inducer with no tuning required. On power levels over 640RWHP the factory intake horn IS a restriction and needs to be replaced with our 3.5” design.
