From what i have read i have different opinions on which one provides better performance results some say the CAI others say the pop chargers but i think the results vary on the cars not all give the same results but i want to see if which one i could get for my 04 6mt coupe. I am looking for the one that gives the best performance i dont really care about the noise it makes
thanks for the help
