  • FMIC piping required; piping modifications may be necessary.
  • A new transition coupler and clamp are needed to fit the 3.5" big bore TB to your piping.
  • An aftermarket MAP sensor is required and must be relocated to the intake manifold or vacuum block.
  • Tuning adjustments are necessary to accommodate the big bore TB and aftermarket MAP sensor.
