How do you install a new shift knob and shift boot on a 2007 Honda Civic Si?

To install a new shift knob and shift boot on a 2007 Honda Civic Si, first, remove the old shift knob by unscrewing it counterclockwise. Next, carefully pull off the old shift boot from the base, which may require removing the center console trim for easier access. Install the new shift boot by sliding it into place, then position the new shift knob and screw it on securely. Finally, reassemble any trim pieces you removed and ensure everything is snug and properly aligned.
