Thanks for the shots showing scale of the various tubes. If anyone is about to do an install or has access to the MAF tube at the sensor, need one last piece of info: What is the INSIDE diameter of the Z28 tube at the MAF Sensor location? On the SS the stock OEM diameter is 3.75" at the MAF sensor.
From the ruler pictures posted looks like the Z28 elbow is 5 inches outside and that would make it about the same 3.75" inside due to ribs.
