    Basically want to know what I put in the title,

    I'm looking to buy a K&N intake, they show two options which is the 63 series aircharger kit, and then the traditional 77 series cold air intake.
    What is the difference between the two, and do any of you have any experience with these products?

    thanks guys!

    The Black tube models will give a little more Power, The Chrome holds in too much heat..But looks nice...
