any one heard of good things about the black diamond intake kit and if i get it i dont need a fuel management system do I?? imput would be great thanks I keep getting snow in my stock intake and I have prefilter on all my vents.
i have a friend that has a 07 m6 and he put the 440 stock air box on his . its lighter than stock and no he didnt have to do any fuel management cause its efi
Cheaper. + you get a heat sheild. I cuty holes out on top of mine and put pre filter over the top. so im still pulling more then enough cold air. Burning More then my old mans 800. 1-2 gallons more.
