new owner of a z

[kenny's 370z]

hello,my name is kenny .just bought my first used 370z yesterday and im already loving it.its an 09 blue 6 speed manual with 58k miles on the clock.im new to the z but not new to modding.hoping to get to know the peeps on this forum and learn all i can about this car to make it all it can be.i did the tb bypass and muffler delete yesterday until i can put a proper exhaust on it.sounds great ! i want to put the best intake that will net me the most gains.i have seen there is not much of a gain from the cai filters that sits behind the bumper.is it true that i would be better off just getting the drop ins and post maf tubes ?
