McLaren F1 GTR Carbon Intake Funnel Intake Manifolds Trumpets NOS

New Old Stock (NOS) carbon fiber intake funnels (trumpets) for the McLaren F1 GTR is a task for the most elite level of automotive collecting. These parts were designed for the BMW-sourced S70/2 V12 engine and are legendary for their role in the F1’s high-frequency induction sound.

The “Unicorn” Status of F1 GTR Intake Parts

Because only 28 GTRs were ever built, these components are almost never found on public marketplaces. Most transactions for NOS GTR parts occur through private brokers or the McLaren Heritage department.

• Material: Exceptionally thin-walled, high-temperature carbon fiber.

• Function: These “trumpets” are velocity stacks designed to optimize the airflow into the 6.1L V12. For the GTR, they were often paired with specific air restrictors depending on the racing series (Le Mans vs. JGTC).

• Identification: Genuine GTR parts will typically feature a specific BMW Motorsport or McLaren “12” prefix part number and often have handwritten inspection markings or yellow “QC” labels from the mid-90s.
