Masata Alloy Aluminium/Aluminum Intake Inlet Manifold Plenum for BMW N54/N55 - Port Fuel Injection Ready (PI/PFI) - Performance Upgrade - Fits E82 1M, 135i E82/E88; 335i E90/E91/E92/E93; 535i E60/E61 - Optional 750cc Injector Kit + Fuel Line

Masata Alloy Inlet Plenum for BMW N54 and N55 – Port Injection Ready

Looking to replace the fragile factory plastic intake on your turbocharged straight-six with something stronger and future-proof? The Masata aluminium inlet plenum is a proven upgrade for BMW N54 and N55 owners who want consistent airflow, durability under boost and an easy route to supplementary fuelling. It swaps directly in place of the OE manifold and is available either as a port-injection-ready unit or bundled with 750cc injectors and a fuel line for simple installation.

Built from high quality aluminium, this performance plenum provides smoother internal flow and a more robust construction than the stock moulded item. Ideal for road and track, stock turbo or hybrid turbo builds, it supports reliable power delivery and crisp throttle response. We have installed these on customer cars and our own projects – feedback on fit, finish and drivability has been excellent.

• Direct-replacement alloy inlet for BMW twin-turbo and single-turbo straight-six engines – N54 and N55
• Port injection ready – choose bare manifold or the package with 750cc injectors and fuel line
• Stronger than OEM plastic – resists heat soak and boost pressure
• Smooth flow path for improved charge-air distribution and response
• Includes additional hardware required for installation
• Perfect foundation for tuned builds seeking consistent fuelling and reliability
