The Snow Performance Water-Methanol Injection System for BMW N54/N55 engines is engineered for enthusiasts seeking reliable octane enhancement and improved thermal efficiency. This complete kit features a custom-designed throttle body spacer plate, ensuring optimal nozzle placement for precise water-methanol delivery. The system includes a braided stainless line and 4AN fittings for maximum durability and straightforward installation.

The Stage 2 kit utilizes the progressive VC-50 controller (ISO 9001 Manufactured), which automatically adjusts injection rates based on boost pressure. Both start and full engagement points are user-adjustable, allowing you to tailor the delivery curve to your engine’s specific needs. The 52mm VC-50 controller also functions as a boost gauge and injection controller, with a 7-color OLED display (Blue, White, Red, Yellow, Orange, Purple, Green) that shows boost, injection percentage, low fluid level, secondary nozzle activation, prime button, and two fault codes. The screen colors can be matched to your OEM gauges or customized.

The included Direct Port Injection Plate is designed specifically for N54/N55 engines, mounting securely between the cylinder head and intake manifold. It comes pre-installed with six 1.5 GPH Snow Performance Hyper-Sonic™ nozzles and hardlines plumbed to a distribution rail for even fluid delivery to each cylinder. The kit also includes OEM O-ring gaskets, all required hardware, a high-flow water-methanol solenoid, engine-specific boost tap, and comprehensive installation instructions.
