i currently have a short ram intake in my 90 accord i saw some power increase and change in sound. i have a cheap knock off tube and a k&n filter. is it worth switching over to a CAI that is custom fit for my car and is CARB legal. is it going to actually make a difference since its tuned for my car? and how much difference does cold air make compared to short ram?

 

also which one would give me a deeper sound?

 

I have been informed that the CAI is a better set up, cooler air vs warm air, some are more quiet due to intake is at the bottom of the fenderwell. Just a minor caution with rainy days and floods.
