Got a 3-inch intake hose that needs to tie into a 4-inch line, this reducer work for that kind of hookup?

That's what it's built for. One end opens at 3 inches, the other at 4, and the whole piece runs 3 inches long. Made from silicone, so it handles heat and harsh conditions better than a lot of cheaper rubber alternatives. Solid choice for bridging those two diameters without a lot of fuss.
