This is a MAF (Mass Air Flow) adapter for a 3rd-party air intake on a 1999 Subaru Forester (and probably other old Subarus too). I designed this around an AEM intake 22-470, but it should work with any 70mm/2.75" tube you can drill or cut a hole into for a sensor. To attach the MAF sensor to this adapter, I used two stainless m5x12 machine screws. I made the holes with tight clearance on purpose so I could "mash" the threads in to place and it worked quite well. To attach the adapter to the air intake, use some RTV Silicone between adapter and intake then bind with stainless steel straps, like these: https://smile.amazon.com/Stainless-Exhaust-TAKSDAI-Locking-Wrapping/dp/B01LX5IXAM Or, you can use zip-ties for a temporary solution which leads me to another point I'd like to make: I'M NOT LIABLE FOR ANYTHING YOU DO TO YOUR VEHICLE! Footnote: There will be pictures soon. I've already tested the design, I just didn't take any photos yet.
