Description

Part #: 146074-8

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.

The LSXHR short velocity stack set shifts torque and horsepower to the high RPM operating range, ideal for high RPM street/strip engines. This stack set fits both the LS3 and LS7 LSXHR manifolds.

MIA's Description

The FAST Velocity Stacks are a set of eight short velocity stacks designed for the FAST LSXHR 103mm Intake Manifold. These plastic stacks can be mixed and matched with other available lengths to fine-tune an engine's powerband. They are a direct replacement for the stacks included with FAST LSXHR Intake Manifolds.
