REVDOP Turbo Inlet B47 – The new performance evolution suitable for BMW 3 Series G20/G21
We are pleased to introduce our latest performance upgrade: the RevDop Turbo Inlet B47 , specifically developed for BMW 3 Series models with B47 diesel engines from the G20 and G21 series . This highly advanced inlet sets new standards in airflow optimization and delivers measurable performance benefits – whether for everyday use, tuning setups, or for ambitious drivers who want to get the most out of their vehicle.
What is the RevDop Turbo Inlet for the B47 engines?
The turbo inlet is an often underestimated part of the intake system that has a significant impact on the efficiency and power delivery of the turbocharger . In their stock configuration, many OEM inlets are designed to meet noise targets and production costs, but they don't fully utilize the potential of the intake air. This is where the new REVDOP Turbo Inlet B47 comes in: It replaces the original OEM inlet with a bionically inspired geometry that improves airflow, reduces pressure losses, and thus supplies the turbocharger more efficiently.
Bionic optimization – More than just a performance buzzword
The term "bionic" comes from engineering and means that natural principles are used to solve technical problems. In nature, structures have evolved over millions of years to optimally direct flows – for example, in rivers, branches, or in animals that glide quickly through the air or water. We utilize these insights in the REVDOP Inlet:
- Instead of sudden changes in cross-section, the shape ensures a continuous, laminar airflow .
- Resonance chambers are removed because they often create turbulence in OEM designs.
- The internal contour was designed to minimize pressure losses and maximize volume – two crucial factors for efficient turbocharger intake.
Compared to the standard inlet, the REVDOP inlet achieves up to 20% less pressure loss and up to 25% more air volume – values that are both subjectively noticeable and measurable, especially with performance increases.
Measurable benefits for your BMW B47
🚀 More direct vehicle performance
Thanks to the optimized air supply, the turbocharger responds faster, resulting in noticeably more direct throttle response and improved acceleration. This is not only beneficial in everyday driving, but particularly relevant for software upgrades (Stage 1, Stage 2).
🌬️ More stable boost pressure
Stable turbocharger pressure is key to consistent power across the entire rev range. The REVDOP inlet helps reduce temperature fluctuations and pressure drops in the intake system.
🔧 Suitable for everyday use & Plug & Play
Installation is incredibly simple: remove the OEM inlet, insert the REVDOP Turbo Inlet, and tighten it according to the OEM torque specifications. No additional modifications to the engine or software are required.
For which models is the REVDOP Turbo Inlet B47 suitable?
The new turbo inlet fits a range of BMW vehicles with the B47 diesel engine , in particular the popular 3 Series of the G20/G21 model lines . These include, for example:
- BMW 318d (G20/G21)
- BMW 320d (G20/G21)
- Other B47-based vehicles depending on the year of manufacture and engine code (e.g. 316d, 330d variants)
Tip: Check the exact engine code compatibility before buying, as there may be different versions depending on the year of manufacture and model.
Technical Highlights of the REVDOP Turbo Inlet
The REVDOP inlet is not an ordinary tuning part – it was developed with efficiency, durability and performance in mind:
- Bionic internal geometry: optimized for laminar airflow and reduced turbulence
- Remote resonance chambers: less resistance, higher throughput
- Increased air volume: more air per unit of time for more stable pressure.
- High-quality materials: heat-resistant and durable, perfect for series and performance use.
Why this upgrade is worthwhile
A turbo inlet is one of the most effective ways to improve the efficiency of your BMW B47 engine – even before considering software or an intercooler. The REVDOP turbo inlet works directly where the heart of the charge air system has the greatest impact: in the intake tract. The result is a noticeable performance gain without compromising everyday usability or reliability.
Conclusion
The new REVDOP Turbo Inlet B47 is more than just a product – it's a sophisticated performance upgrade for every BMW driver who wants to fully exploit the potential of their B47 engine. Through bionic optimization , reduced pressure loss , and increased air volume , it delivers a genuine upgrade that impresses in everyday driving as well as with tuning setups.
