Description

I needed to extend the MAF wiring on my Audi and I could not find a MAF extension adapter. I bought a MAF connector with wiring and 3d printed the other end where the original MAF connector on the car can be plugged in so I can reverse the change at any time. ABS or ASA hold up just fine under the engine bay so far. Did not even try PLA because it's obvious it will not hold. The holes were sized to be able to add pins that are used on breadboards. They work just fine for this. You can plug them in like shown and epoxy them in that position (JB Weld / Bison metal or similar will do). Check your MAF wiring harness to see which pins are used and fill the holes with epoxy (or in tinkercad before printing) to avoid water going in.
