No i want prove that it doesn't lose power with the cai/ram the most systems lose power on the f56 cooper s. That is because the system already is very good it takes cold air just before the radiator and it is a short ram system couldn't be better. The only one making power is armaspeed.... Now i do like a cai for sound of the engine and bov sound. So hey you just add your stripes and leds angib , you will be the tuner of the day. Hahahaha crazy how some people react. Thinking they know everything.
