The ARM Motorsports S55 Silicone Charge Pipes are engineered to eliminate one of the most common failure points on the BMW S55 engine: the fragile OEM plastic charge pipes. Factory S55 charge pipes are prone to developing hairline cracks at the seams, causing boost leaks that rob the engine of power and force the turbochargers to work harder to maintain target boost levels. The ARM Silicone Charge Pipes replace these problematic factory components to deliver maximum reliability and consistent power under all driving conditions.

Unlike aluminum charge pipes, which conduct heat from the engine bay into the charged air stream, silicone piping offers far superior thermal insulation. This keeps intake temperatures lower, helping the S55 maintain repeatable performance — especially during sustained pulls or track sessions. With a 5-layer steel-reinforced construction, these pipes are designed to withstand extreme boost pressures well beyond 60 psi.

Precision CNC-machined turbo adapters ensure a perfect, leak-free fit to the compressor outlets, providing seamless airflow from the turbochargers to the intercooler. Whether your vehicle is stock, tuned, or running a built motor, the ARM S55 Silicone Charge Pipes deliver the durability and performance needed for aggressive street driving or high-boost applications.

Each kit includes silicone charge pipes, CNC turbo couplers, and clamps for a complete installation. Backed by ARM Motorsports’ lifetime warranty, these charge pipes are a must-have upgrade for any S55-powered BMW.
