Wagner Tuning BMW/Toyota B58.2 Turbo Inlet for Hybrid Turbo Chargers
The Wagner Tuning Turbo Inlet is a direct upgrade for the B58.2 engine found in modern performance BMW and Toyota models. It has been developed to support hybrid turbo conversions, where a larger compressor wheel is fitted to the standard turbo housing, allowing more air to flow into the engine for greater power potential.
Manufactured as a complete aluminium adapter with a durable powder coated outer finish, this inlet replaces the restrictive factory pipework with a smoother, larger bore alternative. With a maximum internal diameter of Ø 62.5mm, it is shaped to suit hybrid turbo setups and helps keep airflow consistent at higher boost levels.
Why fit a larger turbo inlet?
The standard inlet on the B58.2 engine becomes a bottleneck once the turbocharger is upgraded. A larger inlet reduces airflow restriction before the compressor wheel, which helps the turbo work more efficiently. In practical terms, this supports the power gains from a hybrid turbo and improves throttle response under load.
