I did the removal of the stock intake within two hours that seemed eternal. I got stuck removing the air director (instruction 16). There is one instruction missing that I cannot understand (I'm a newbie at this things). What is # 10: "Remove the two bolts screws securing the fuel pump resistor ballast to the driver's side frame rail" What the hell is that. I don't even know what is the "fuel pump resistor ballast". Help please! I guess that I have to do this before doing the installation of the MazdaSpeed intake.
