  20. Remove the intake temperature sensor from the original assembly and install it into the rubber mount on the new pipe. It takes a little time and effort but the sensor will fit. I put the grommet over the sensor first, then stuffed the grommet into the hole with a small flathead screwdriver. Make sure that the sensor tip has a clear pathway for the air to flow over it inside the pipe.
