When upgrading to higher power levels, stock fuel injectors are short lived as they simply cannot deliver enough fuel to safely run more than ~380RWHP. These Nismo injectors are engineered and designed to flow larger amounts of fuel to keep up with the demand as airflow increases. Injectors are precision made and have exceptional calibration directly from the factory.

These upgraded fuel injectors fit directly into early style fuel rails on 90-94 twin turbo which are the same rails on 90-92 normally aspirated models.

New OEM Nissan upper and lower injector o-rings as well as the seals between the fuel rail and lower intake plenum (18 pieces) are available in a complete set as an option below.
