The TiAL Sport 3.25in to 4.00in silicone reducer supplies a reinforced, short-length transition between larger intake and boost piping sizes. Built from 4-ply poly and measuring 3 inches long, it comes in a glossy red finish to match visible plumbing. Use it when you need a tidy diameter change for intercooler, turbo, or intake runs without adding long couplers.
