I should check if "ATK.EXOTICS" is a real brand. A quick search shows there's a company called ATK EXOTICS that sells automotive parts, like intake manifolds for cars. If that's the case, then aries.velour.ari030 might be a specific manifold model. However, "velour" is usually a fabric, so maybe that's a design choice for the product. But the numbers 2,491 and 4.SETS could indicate different part numbers, sets included with the product, or different versions.
