Narrative:
After initial climbout; the right engine started to surge. The other pilot and I both noticed that the oil and cylinder head temperatures also started to rise. With no clear explanation of the cause; I performed a precautionary shutdown of the right engine. We informed ATC and declared an emergency when switched to approach control. They asked us if we needed crash fire rescue equipment and; not knowing the extent of the situation; we requested the services. We proceeded to land without further incident. After inspection by a mechanic; it was found that the right magneto had partially failed.
