Plazmaman N54 Intake Manifold - BMW N54 (135i, 335i, 335is, 535i, Z4)

Product Details

For those aiming for the 700–1000+ HP range, this manifold serves as a critical fueling hub. It is specifically designed to accommodate high-flow secondary fuel rails, allowing for a Port Injection (PI) setup. By moving the fuel injectors into the manifold runners, it bypasses the limitations of the factory Direct Injection (DI) system, allowing for the use of high-ethanol blends (E85) without the risk of leaning out at high RPM.

Key Features

• Port Injection Ready: Includes a dedicated high-flow fuel rail for secondary injectors.

• Optimized Runner Length: Balanced for mid-to-high RPM power bands, perfect for large single-turbo conversions.

• O-Ring Sealing: Uses Viton O-rings at the cylinder head interface, eliminating the need for messy liquid gaskets or flimsy OEM seals.

• Lightweight Design: Strategic CNC pocketing keeps the weight significantly lower than heavy-duty cast alternatives.

Specifications

• Fuel Rail: Included (Anodized Billet)

• Injector Fitment: 14mm O-ring (Standard Bosch style)

• Engine Fitment: BMW N54 (335i, 135i, 535i, Z4, 335is)

• Sealing Method: Viton O-ring Grooves

• Weight: Approximately 25-30% lighter than traditional cast manifolds
