Some intakes are acceptable to run without a tune, such as the K&N. That intake doesn't change the diameter, therefore flow dynamics are unchanged, meaning no tune is required. Is it recommended? Oh yeah. Cobb does require a tune, so please consider your engine management before doing this or any intake.
