Oil catch tank suitable for MX-5 ND from Verus Engineering. The oil catch tank captures oil vapors from the crankcase ventilation and valve cover ventilation, filters them and returns the filtered gases to the intake system. The result is a clean intake tract with no oil coking. The oil coking normally settles in the intake system and thus clog the intake. This in turn results in a drop in performance. To install the catch can, the Sound Tube Delete must be used, which can be found under "add additional parts".
