how can i change the sound.
CAI will give a unique extra sound to your vehicle. BUT do your research on CAI first. K&N isnt always a good fit for the make of the vehicle. example: on the 05-08 hemi 300C the ONLY CAI that gives more hp and better fuel efficiency is a stage 2 AFE CAI. K&N actually causes a loss in hp for the vehicle. try to find an independent research for your vehicle before buying a CAI
