A Japanese brand TETRX molded this soft silicone meant for Lancer Evo4 Bonnet air outlet vent.
This idea came from Lancer Evo5, when the Bonnet had a contour that raised up the surface in front of the Bonnet air vent to create more Vacuum, to create an easier vent-out of hot Air from the engine bay.
TETRX made them for Evo5 as well but Discontinued since Don't know when
We found a new piece "nearly forgotten" in our storeroom..😅
