Offered here is a used OEM HFS4-v3.1 / HFS-4 Methanol Injection Kit (7835046) pulled from a BMW M5. This aftermarket-style kit is designed for the 4.4L twin-turbo V8, injecting a methanol/water mix to cool intake charge and suppress detonation. A failing system may cause reduced power or knock under boost. It also replaces 7845046.
