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.

Unlock the intake performance your Pure 900 build deserves. The BMS Competition Cold Air Intake is engineered specifically for Gen 2 B58-powered BMWs running the Pure 900 turbocharger, bringing an OEM-plus look, an enclosed airbox with a clear inspection window and the addictive induction sound of an open cone. Developed on road and track, it combines a smooth 4 inch intake tube with a high-flow renewable inverted cone filter and velocity stack to maximise airflow while helping keep intake temperatures down by retaining the factory heat shield and utilising the OEM cold air ducting.

  • Purpose-built enclosed intake system for Gen 2 B58 cars with the Pure 900 turbo
  • Smooth 4 inch intake pipe replaces the OE accordion hose and resonator to reduce restriction
  • Dual cold air feeds: uses the OEM duct plus a large cold-side opening for extra fresh air
  • Renewable inverted cone performance filter with integrated velocity stack for efficient flow
  • Airbox lid with clear window for quick, tool-free filter inspection
  • Retains the OEM heat shield to help maintain low IATs
  • Optional welded 19 mm PCV fitting available for oil catch can setups
  • Compatible with OEM or BMS Billet Strut Braces
