I Am Interested In Doing Some Minor Alterations To My 2004 Fx4. I Would Like To Know What The Thoughts On Headers,exhaust And Intake. Specifically Are Headers Alone Enough On The Exhaust Side And Is The K&n Fipk Worth The Dough For The Intake System?

 

to get the best bang for your buck, you really need to go with a tuner. one of the most favorite used by the people on this site it the edge attitude. sure, headers, intake will do a little, but you need to get into the engine settings to really be happy. going with an aftermarket intake on these trucks is rather controversial. some like them, others say its just a big waste of money since oem supplies more than enough air. so some searches and you will find plenty of opinions and advice on how to spend your money !!!

 

I agree with mattd17 to see the biggest difference go for a tuner/programmer or a chip but a free flowing exhaust helps

 

A programmer is with out a doubt the first thing to get. You can feel the power. Then to make more air go in and out,get a CAI and a cat back exhaust. To get the most out of a set of headers, the Y pipe should be changed out for true duel exhaust to get rid of the restriction.
