They both were used on my car - MK3 with 1JZ
Both of these BOV's work perfectly sweet...and was tested on another car yesterday.
One is the older model with the trumpet and the one attached to the grey pipe is the current model. There are 3 attachments: 1 for plumb back, 1 with the filter and 1 for fully sik atmo sound.
Please make offers. I have interest in the bov with the grey pipe...been offered $190 for it.
