At 1290' experienced partial power loss from 26' manifold pressure down to 20' manifold pressure, declared an emergency, returned to the field for landing. We were cleared from approach control. Asked approach for 118.2 (tower frequency). Was approved for landing. Landed with no incident. The air intake boot had collapsed by half of its inside diameter, causing engine to starve for air. This did not show up in runup.
