2 long obvious. They go over the airbox. The capital S goes from the turbine to the upper breathing reservoir. The small S stands for power steering. The one with 2 90Β° elbows and a slightly larger side goes from the inlet to the PCV hose in front of the intercooler. Small 90 from upper airway to block (good luck, that's the wrong size) Last one, I have no idea but I'm using it for another hose from the power steering pump to the power steering pump. It's the wrong shape, but it works. 1 starβ¦
