Roto-Fab makes a cold air intake for the G8 V6 similar to the K&N system. Better depends on who you ask. Oiled media filters require periodic re-oiling and an over application of the oil could potentially damage the mass air flow sensor. However, this probability is low since oil is only applied to the outside of the filter. The K&N recharge oil comes in both a spray can and squeeze bottle. Prefer the aerosol can. On the other hand, the dry filter doesn't require re-oiling and is more convenient to maintain i.e. either vacuum and reinstall or wash and dry.
