S410SX S478 78mm Turbocharger for Caterpillar 3406B C15 C16
The S410SX (also sold as S478) is a 78mm billet-wheel turbocharger for the Caterpillar 3406B, 3406C, C15 and C16. It runs a larger compressor than the stock single turbo and a T6 twin-scroll 1.32 A/R turbine housing, which makes it the common choice when a shop wants more airflow and top-end power out of these 14.6-15.8L engines while keeping a bolt-on fit. Our S410SX is built new to OEM-spec with a billet compressor wheel and balanced before it ships. We match the part number against your old turbo and engine serial before the order leaves the warehouse. We supply repair shops, fleets and distributors with single units and bulk orders.

S410SX S478 Turbocharger: Sizing, Fitment and Install Notes
The S410SX, sometimes badged S478, is the go-to single turbo when a Cat 3406 or C15 needs more airflow than the factory unit gives. Here is how to spec and fit it.
What it fits and why shops choose it
This 78mm frame bolts to the 3406B, 3406C, C15 and C16 with a T6 twin-scroll inlet. The larger compressor moves more air than the stock turbo, so it supports higher fueling and more top-end power while still installing in the factory location. It suits trucks pulling heavy and engines built for more output.
S410SX vs the smaller stock turbo
If your engine ran a smaller single turbo, the S410SX is an airflow step up. To use the extra capacity, your fueling and exhaust need to match it; fitted on a stock tune it still bolts on and runs, just with more headroom. Confirm your housing A/R and inlet flange before ordering.

Signs the old turbo is done
Low boost and power under load, dark smoke, a new whine, oil at either wheel, and shaft play you can feel by hand all point to a worn turbo.
Before you install
Most failures on these engines start in the oil supply or the intake. Check the feed and drain lines are clear, prime the new turbo with clean oil, and inspect the intake for debris from the old unit. Fixing the root cause protects the new S410SX and keeps the warranty valid. See our quality process for how each unit is tested.
