The ARM S55 Silicone Charge Pipes allow you to maximize power on your S55-powered BMW by replacing the OEM charge pipes known for cracking. Silicone charge pipes benefit the S55 engine over their aluminum counterparts by providing an extra layer of insulation. Aluminum charge pipes conduct heat very easily between the engine bay and the charge air from the S55's turbos to the intercooler. In contrast, silicone charge pipes significantly improve insulation between these two areas.

The stock S55 charge pipes are notorious for developing hairline fractures at their plastic seams. These fractures or cracks are unnoticeable to the naked eye, but under boost pressure, they open up, leaking the desired charged air into the engine bay and consequently robbing your S55 of its full power potential. In addition, these leaks will cause boost leaks which cause your S55's turbochargers to work harder to hit and maintain target boost pressure.

The ARM S55 Silicone Charge Pipes replace the OEM plastic S55 charge pipes, ensuring that all of your charged air transitions from the turbos to the intercooler.

CONSTRUCTION

The piping of ARM S55 Silicone Charge Pipes is constructed of 5-layer steel-reinforced silicone, allowing them to handle the boost pressures over 60psi. We rely on our ARM S55 Silicone Charge Pipes to contain boost on our project F80 pushing over 30psi. So whether you are a stock or fully built motor, the ARM S55 Silicone Charge Pipes will be able to handle whatever you throw at them.

The ARM S55 Silicone Charge Pipes utilize precision CNC machined adapters for seamlessly mating up to the turbochargers' compressor outlets, creating a secure, leak-free seal.
