Description
The Dinan Turbo Inlet Pipe is designed for 2025+ BMW M340i and M440i models equipped with the Gen 3 B58 engine, delivering improvements in turbocharger airflow, efficiency, responsiveness, durability, and induction sound. Turbo inlet pipes serve two distinct purposes: optimizing turbocharger efficiency and responsiveness by allowing the turbocharger to ingest more air through a larger, unobstructed flow path, while also increasing the sound produced by the turbocharger and intake system.
Dinan delivers both benefits with a purpose-built turbo inlet that replaces the weak and failure-prone plastic factory inlet with a more robust carbon fiber construction. OEM+ fittings are utilized to ensure proper fitment and provide a direct replacement for the OEM turbo inlet.
Beyond material quality and fitment, the Dinan turbo inlet improves the characteristics of the primary element in the system: the inlet pipe itself. The factory turbo inlet incorporates additional features, including multiple components in some applications, that introduce flow restrictions and turbulence while simultaneously reducing turbocharger noises. These restrictions are unwanted for optimized airflow but can be easily addressed by removing the various resonators and enlarging and optimizing the airflow path for a more uniform flow.
The result is a turbo inlet that delivers increased airflow, improved turbocharger efficiency, reduced workload on the turbocharger, and enhanced turbo induction sound. Whether the priority is improved efficiency and flow optimization or a more visceral and pronounced turbocharger soundtrack, the Dinan Turbo Inlet Pipe delivers both benefits.
Features
- Increased turbocharger efficiency and reliability through maximum unimpeded and uniform airflow.
