This is a replacement for the 2.5 bar units in the N9TEx engines. May also work with the 1985 N9T, which originally used the 3 bar FPR. Increased performance, especially at higher boost levels are claimed by others for this part. Nice black enamel finish in case anyone looks behind your intake manifold. :) New. Peugeot P/N 156382 3 bar or replaces P/N 156377 2.5 bar. Compare elseWHere at $131.70/$113.20
