Hi! I have the high power rx8 and on the vfad solenoid there i had the hose disconnected, so i plugged it back but what should i do with the other plug? Does it needs to be plugged to be air tight or just as is wented?
The "plug" that people see is actually called a "silencer" by Mazda. It doesn't actually seal. It's there to allow the VFAD vacuum actuator system to return to atmospheric pressure.
Below 5500 RPM, the solenoid is de-energized and the VFAD actuator is kept at intake pressure (vacuum). Above 5500 RPM, the solenoid is energized and it allows the VFAD actuator to return to atmospheric pressure.
If you cap that port, the VFAD will never return to atmospheric pressure and it will never open.

Just ask a local dealer and see how much this costs.
The stealership around here is costly as .... so if it is just something that vents that nipple of the actuator to the atmosphere iwill just add some cheap ebay fiter and it will be looking awesome :D
I recently installed a short ram intake on my car and made the mistake of throwing away the sensor and the vacuum chamber. Could someone tell me where I could find a new one because I haven’t been able to find a new one. It’s throwing a CEL and I need a fix whether it’s finding the part or removing the whole vfad system
