Spun from 5052 aluminium to a parabolic profile, this velocity stack is a great way to adapt a filter with a 6" (152mm) opening to a 3.5" tube or to reduce inlet losses on a 3.5" (89mm) tube or turbo inlet.
Often, spun velocity stacks don't feature beads to help retain filters, leading to poor filter fitment. And with its 1.3mm (0.05") wall thickness, it's perfect for welding to industry-standard 0.060"-wall aluminium tubing if making a custom intake setup.
ACUiTY's velocity stacks feature a rolled bead on the large end and a flared outlet on the small end to ensure your filter and coupler stay attached. A durable, matte black, painted coating is applied to each velocity stack for corrosion protection.
