We are providing this option for the people that already have some of the items included in our air intake kits and for people running less common engines. Just select the items you need from the drop downs.
Air Intake Panel: This panel is used to mount a 3 inch cone filter. It uses existing weld nuts to attach. It is made of stainless steel.
Air Filter: We offer two 3 inch cone filters. A budget option and a K & N filter. They both have about the same performance.
Silicone Elbow: This elbow usually goes on the intake panel to direct the air towards the intake. Its a 3 inch elbow. It comes with two hose clamps.
Throttle Body Reducer Elbow: This elbow is used on all Subaru throttle bodies. It is a 90 degree elbow that goes from 2.5" ID to 3" ID.
3 Inch Intake Hose: Generic 3 inch intake hose. Comes in a 21" length.
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.
