Description
The Audi S4 engine is a premium 3.0L turbocharged V6 engineered for sophisticated performance, producing 330–354 hp and 325–369 lb-ft of torque depending on generation. This powerplant exclusively powers Audi S4 Sedan (B8/B9), Avant, and Cabriolet models from 2009–present, combining turbocharged efficiency with Audi’s refined Quattro all-wheel-drive platforms. The S4 engine features direct fuel injection, variable boost control, and precision engineering for seamless power delivery.
The S4’s turbocharged V6 defines modern premium performance characteristics across generations. For alternative turbocharged options, explore the Audi RS3 engine with five-cylinder configuration and higher horsepower output. Transmission compatibility is optimized with automatic options. All units dyno-tested and warranty-backed.
S4 engine fitment requires matching your specific generation. The B8 supercharged and B9 turbocharged are fundamentally different engines with different induction systems, intercooling approaches, and management interfaces. Our VIN verification confirms the exact S4 engine for your generation before it ships.
Audi S4 owners comparing a used engine, a remanufactured engine, and an OEM engine for the 3.0 TFSI need the Audi-specific boost system preserved correctly. A used Audi S4 engine from a verified low-mileage donor gives you the factory 3.0 TFSI as an OEM engine — supercharged or turbocharged — with original Audi calibration, original induction system, and original S4 performance character intact. No remanufactured engine from an A6 or Q5 3.0T core delivers the S4-specific factory assembly. Choosing a used S4 OEM engine restores the factory performance that separates an S4 from a standard A4.
Every used Audi S4 engine ships with up to a 90-day warranty and arrives within 2 to 5 business days. Installation is not included. Audi specialist installation is recommended. These are genuine Audi OEM engines, and we stand behind every unit.
