LSXHR 103mm Intake Manifold Short Velocity Stack
The LSXHR short velocity stack shifts torque and horsepower to the high RPM operating range, ideal for high RPM street/strip engines. This stack fits both the LS3 and LS7 LSXHR manifolds.
The LSXHR 103mm Intake Manifold's interchangeable velocity stacks allow for the fine tuning of the LSXHR's powerband. Available in tall, medium and short, these stacks can be mixed and matched to improve performance and also to fine tune an engine on a cylinder by cylinder basis.
