    Weiand and John Lingenfelter collaborated to develop this killer aluminum intake manifold for serious LS1 horsepower. It's the perfect manifold for big motor combinations and forced induction applications. The removable bottom plate allows access to the internal passages. The cast aluminum design is more durable than the factory composite. ''Boost'' or ''spray,'' this manifold can handle the added stress of forced induction and nitrous injection. It contains extra material for flow modifications (hand, CNC, or Extrude Hone) to feed hungry modified LS1 engines. The aluminum manifold's thicker walls can also be machined for NOS fogger nozzles or other modifications.

    Features

  • Idle-6200 RPM power band
  • Cast aluminum design
  • Satin or polished finishes
  • Extra material allows for flow modifications
  • Thick aluminum walls can be machined for Nitrous
  • Underside panel is removed to facilitate access to runners

  • Does Weiand 300-111 fit your vehicle?

    Can you bolt bigger throttle bodies to this intake over stock ls1? If so what sizes fit?

    Asked by: Dmorri
    This is designed for the stock throttle body, but can be changed within 10 mm of the original diameter.

    Motor Vehicles

    WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm.

    WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
