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. We're upfront about this — please be sure of your purchase before ordering.

Give your Gen 1 BMW B46 B48 or Toyota GR Supra 2.0 the sound and response enthusiasts want with the BMS Charge Pipe and Turbosmart Raceport blow off valve kit, available from Nforcd. This premium aluminium charge pipe upgrade replaces the factory charge air duct and adds an atmospheric BOV for that addictive turbo whoosh while helping to reduce compressor surge and support reliability at elevated boost.

  • Turbosmart Raceport atmospheric BOV dump valve for authentic turbo sound
  • High-gauge aluminium charge pipes with CNC machined throttle body and turbo flanges
  • Matte black textured finish and OEM-style fitment
  • Increased internal diameter for improved airflow
  • Integrated 1/8 NPT ports for boost gauges or methanol and water injection
  • Includes heavy-duty silicone coupler, T-bolt clamps and full installation hardware
