MY 99 / 00 wrx
GFBBOV3 is a 2-stage hybrid blow-off valve - half external venting and half plumb-back. It is purpose designed for airflow metered vehicles, where the owners want that distinctive blow-off valve "pssht". At light load conditions, purge air is directed back after the airflow meter - virtually eliminating the usual problem of stalling and excessively rich mixtures. At high pressure - when maximum venting is required - "the hybrid unleashes an external venting trumpet" to give the desired sound effects.

Does not come with the two bolt pipe fitting for the inter cooler
$100.00
