Yes and No. In general. the only things that cannot be be removed with the Gen-II kits are the pressure sensors. Everything on a "3 Valve 4.7L" vehicle is located underneath the intake manifold, so unless you already have it off or just REALLY want to eliminate it all the system components are normally just left in place.Maybe I’m missing something, but, can I completely remove the SAIS hardware installing the full gen 2 kit? Less clutter in the engine bay is a desire of mine. Plus with it being bypassed what’s the point in keeping it? Mine is functioning perfectly on our ‘08 470 but I like preemptive maintenance rather than reactionary maintenance.
If you did want to remove everything on a 3 Valve vehicle you would just need to unbolt the pressure sensor from the main electric air switching valve and leave it connected. You could then remove the air pump, the main electric air switching valve (sensor remaining), the two No.2 vacuum actuated air switching valves at the back, the rubber air tubes and the stainless air tubes that go to the exhaust manifolds. The air injection control driver is removed and replaced with the Gen-II unit itself but the pump fuse can also be removed. There is a large 2 wire connector that gets one of our custom plug caps but it could be removed as well if you really wanted to. Just cap it and tuck it out of the way though.
If you wanted to remove the ENTIRE system on a 3 Valve 4.7L you would need a GenII-3V kit and a PSRW (harness only and you can reuse your existing sensor with it) that would move the factory sensor from under the intake manifold to the ECM where you would wire it in with the three wires of the GenII-3V kit. Then you would have absolutely nothing of the secondary air system remaining under the intake manifold except two disconnected plugs.
