    Edelbrock 7142 Details

    The Edelbrock Pro-Flo XT LS3 EFI intake manifold features a large plenum with long runners to give you the most horsepower and a broad torque band from 1500-7000+ rpm. It features a 90mm throttle bore opening that can be ported to 105mm as needed. A stock LS3 MAP sensor or Edelbrock 325-36019 can be mounted directly to the manifold. This is not intended to be used on late-model vehicles due to hood and cowl constraints. In testing, the Pro-Flo XT LS3 intake manifold made 16 horsepower more, and the peak power point also increased by 500 rpm compared to a competitors plastic design. The Pro-Flo XT LS3 intake manifold is the best choice for your boosted or nitrous powered LS3 engine.
