Heads-up on cancellations & returns: if you cancel an order or return an item, you won't get back 100% of what you paid. We apply a 10% restocking fee, the outbound shipping is non-refundable, and we have to pass on Shopify / PayPal payment processing fees; these aren't returned to us when we refund you. International orders also lose on exchange-rate spread in both directions. If the original packaging is damaged or missing, a reboxing charge applies. For international orders specifically, if you refuse to pay our shipping invoice or supply a prepaid label after placing the order, the same deductions apply.

High performance charge air hot side hose for BMW F series N55

Replace the compressor outlet to intercooler connection on your N55 engine with this Forge Motorsport reinforced silicone boost tube. Built for reliability under heat and pressure, this charge air hose gives a tougher, smarter OEM style finish while helping prevent boost leaks on tuned and standard cars alike.

Constructed with a fluorosilicone inner liner and multi ply reinforcement, it resists oil mist, OAT coolants and sustained boost pressure. It is a direct swap for the factory hot side joiner on BMW F series N55 models, retaining the original seals and clips for a perfect fit. Backed by the Forge Lifetime Warranty for peace of mind.

We have installed this on customer vehicles and our own builds, and feedback has been consistently excellent for fitment, durability and overall quality. Pair it with a Forge charge pipe for a complete, leak resistant charge air system.

Why this upgrade makes sense

  • Fluorosilicone inner layer resists oil contamination and modern coolants for long term reliability.
  • Thick wall multi layer silicone exceeds factory specification for heat and pressure tolerance.
  • Direct replacement for the turbo outlet to intercooler inlet connector to reduce the risk of splits and ageing.
  • Factory style fit with an OEM plus look that tidies the engine bay.
  • Supported by the Forge Lifetime Warranty for confidence on road and track.
