Installed stage 2 two days ago. Maybe an hour of my time, being the first time to remove those sections under the hood necessary to get to the sensors.

No splicing of any wires. All wires hidden.

Skill level from 1-10: 2.
Tools:
1 8mm socket (6 bolts holding plastic hvac cover).
1 #2 Phillips screwdriver (2 screws holding shroud at rear of engine bay).
1 small blade standard screwdriver (to help remove plugs from the 4 sensors).
3 zip ties (optional to secure new wire loom)
