    1991 Chevrolet Blazer EFI Systems

    The K5 Blazer received a redesign in 1973 which ran mostly unchanged until 1991. GM must've known it had a winner as they applied the old adage of, "If it ain't broke, don't fix it." While the Blazer is plenty capable in stock form, you can take yours to the next level with a variety of parts from us to make it more capable, on-road, off-road, and anywhere in between.

    Wet nitrous systems are the most popular option since they provide the extra fuel to support the added nitous, and don't require any modifications to the fuel injection system (no custom programming of the computer to add fuel when the nitrous is activated). Dry nitrous systems are generally used in racing applications in combination w/ the HP or Dominator ECU w/ custom calibration to add the extra fuel using the fuel injectors (in an EFI application).
