Yes that is true. Once a season should do the plugs and oil change even if you do not get the miles on the car.

Did some research and the 997 crowd seems to gravitate to the Bosch F5DP0R with a 30k change interval. Seems highly recommended from the larger boosted community as well. As my car is a daily driver, albeit with A28, 1000cc, and tune, the longer interval is appreciated.
