For those who are serious about making power, this Stage 2 intake manifold will allow you to take it to the top. For custom high horsepower builds only, requires custom tuning. Not recommended for daily drivers. With four extra conventional injector bungs you can add way more fuel to feed the engine. This is the option to take it beyond what just the RS4 injectors can do alone. This intake manifold is also equipped with four 1/8" NPT threaded ports so you can use direct port methanol injection for the ultimate power package. Don't let a plastic manifold or RS4 injectors hold you back any longer!
Notes: Must use bosch style injectors. Injectors and methanol nozzles are not included. External fuel controller required to tune port injectors.
