Thread: What's the right product?

  1. #1

    Default What's the right product?

    I'm interested in getting a little more HP without going with a complex system, which I came across NOS as a possible solution.
    I read and watched videos on an EFI single jet 'dry' system for persons who want to keep their vehicle OEM.

    A little confusing; the product (05122NOS) description says stock fuel pumps and the ECU should provide enough fuel.
    But the video shows a segment about increasing the fuel amount a couple of different ways.

    Is the 05122NOS the correct product for a 2.0L, horizontal 4 cylinder, high compression engine (D-4S) in my 2013 Subaru BRZ?
    Or is there another part number? This engine is already dual direct and port injection. Any assistance would be appreciated.

    N2O fuel enrichment is accomplished by increasing the engine's EFI fuel pressure with the NOS Nitrous Pressure Regulator. (Read top of page 5.)
