The original MAF sensor is side on. where my design will be 90+ degrees. Reason I went for 90+ degrees is that the will be next to no structure in the sensor once its cut up. There are 3 wires from this block to the sensor part in the air flow. Encasing it in a box gives it support, made some grooves for ventalation as the sensor block has holes on it.
The air flow measuring part of the sensor, 3 wires from the sensor. I need to extend these for the new oval shape.
