Thanks for the links, mikefocke and 78F350. I'm assuming in my '99 base, they go in the top of the air intakes, but don't inhibit airflow measurably.

78F350, I'll buy a full set of the cheapies for your car and mine and all the pizza and beer you can handle if you come over and show me how to hook them up without frying my car.
