    Difference between LS1 intake and LS6 intake
    -On the LS1 the bottom of the intake is not flat., but they have the X shaped bracing between the ports.
    -On the LS6 manifold, it has a flatter bottom and 1 verticle w 2 horizontal ribs in the area between the ports.
    -The STOCK LS6's also do not have EGR provisions, unless they are fabricated.

    I dont think theres a difference between the two. I would just buy a ls6 intake to gain and see a difference

    It wont make any difference. It is still an LS1 intake. Upgrade to the LS6 and sell the LS1 intake on ebay. that's why i did and I got 100 bucks for my old
    LS1 intake with the fuel rail. So at the end my brand new stock LS6 intake with new fuel rail cost me around 245 bucks.
