This coupling allows you to run a custom air intake assembly by giving you a location to mount your MAF and a location to plumb in your crank case ventilation.
MAF Coupling Fitment:
You must choose your model year or MAF part number from the drop down. You kit will vary based on your selection.
- 1990-2000 Subaru: You will recieve a panel with holes drilled in it. You will attach your Subaru MAF housing to this panel with through bolts through said holes.
- 2001-2004 Subaru: Aside from some 2004 models, Subarus in this MY range did not use MAFs. Therefore, the coupling you recieve will only have a single port with a nipple to be used for crank case ventilation. Your air pressure sensor (if present) can be installed into the 90 degree boot that is installed on the throttle body. Do this by drilling a hole and pressing in the sensor.
- 2004-2009 Subaru: You will receive a coupling that fits your MAF (PN:22680AA310). This coupling will also have a nipple to be used for crank case ventilation.
- 2010-2012 Subaru: You will receive a coupling that fits your MAF (PN:22680AA380). This coupling will also have a nipple to be used for crank case ventilation.
- Bostig Conversions: You will receive a coupling that fits your MAF (PN:98AB-12B579FA). This coupling will also have a nipple to be used for crank case ventilation.
Please Note: Sensors NOT included.
