Perrin inlet
The Perrin inlet looks incredible compared to my old 3in. AP hard inlet sticking out from under the manifold, however, install was not the easiest. Found it to be much easier to install with the manifold removed. Internal diameters were both 3in, but the Perrin is massive compared to the AP making fitment under the intake extremely tight. As for performance improvement, I don’t know if it flows better than the AP inlet as I am in the middle of pro tuning for a lot of mods that went on the car, but it looks a lot nicer.
