_x000D_

Our LS AirMax intake manifolds feature either a single or dual plane design that makes them perfect for low end torque, yet still pull all the way from 1500 to 6500 RPM! They have low profile 4150 square bore flanges meaning a carburettor or EFI throttle body will fit under the bonnet of most vehicles. EFI versions include fuel rail kits ready to go. Available in a natural or black powder coated cast aluminium finish.
