Acuity 3.5" ID Velocity StackSpun from 5052 aluminum to a parabolic profile, this velocity stack is a great way to adapt a filter with 6" (152mm) opening to a 3. 5" tube or to simply 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 aluminum tubing if making a custom

Spun from 5052 aluminum to a parabolic profile, this velocity stack is a great way to adapt a filter with 6" (152mm) opening to a 3.5" tube or to simply 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 aluminum 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 make sure your filter and coupler stay attached. Additionally, a durable, matte black, painted coating is applied to each velocity stack for corrosion protection.

    Great vest for a great price!
    This vest is more slim fitting, stylish, & flattering than many vests. It fits as expected, but it is adjustable in the back, so you do have some wiggle room to tighten & loosen it if you’re unsure about the size. My son wore this vest to homecoming. He is 5’ 10” & 150 lbs, & the size small was a good fit.

    Great Quality Vest
    Great quality vest versatile for all occasions. I personally felt it ran a bit tight (I ordered a large and felt like I was sucking in a bit the whole time) but I think an XL would have been too big. Overall impressed and happy with purchase.

    BUTTONS LIKE A SMALLER SIZE. GOOD QUALITY.
    DESIGN IS EXCELLENT. QUALITY IS FINE. I WEAR A LARGE, BUT THIS VEST, IN A LARGE, DID NOT ALLOW ME TO BUTTON ... AS IF IT IS A MEDIUM FIT. WILL RETURN, BUT IT IS A VERY GOOD VEST OTHERWISE.
