Add more fuel via port injection while increasing airflow!

Replaces your weak factory plastic N54/N55 intake manifold with a direct fit high flow high strength aluminum manifold. Features port injection bungs located on the top of the manifold for easy access and optimal injector spray pattern, expansion vacuum ports perfect for larger diameter blow-off valve references, additional gauges, Hobb's switches, and any other expansion you can imagine. Includes high-quality o-rings and all required hardware. Available with required port injection hardware (calibrated injectors, plug and play fuel line), or ala-cart without the extra fueling hardware. Fits all N54 and N55 Engines.

The Burger Motorsports JB4 Port Injection Controller attaches to the JB4 allowing it to directly control both traditional port injection kits and WMI port injection kits.
