BMW M4 G82 S58 Engine — The PlatformThe BMW S58 is a 3.0-litre twin-turbo inline-six and the heart of every G-chassis M car: M4 G82, M3 G80, M2 G87, X3 M, and X4 M. In Competition spec it produces 503 hp and 479 lb-ft of torque from the factory — but with a closed-deck block, forged crank, and twin mono-scroll turbos, it was built to handle significantly more.That headroom is why the S58 has become one of BMW's most tuned modern engines. A well-calibrated ECU flash can unlock serious power without opening the engine.→ Browse all BMW M performance partsS58...

YPG Motorsport is expanding beyond ECU calibration and into purpose-built suspension components — starting with our own line of performance lowering springs and height-adjustable springs for the BMW G8x platform. Why We Built Our Own Springs Every M2, M3, and M4 that comes through our shop for tuning leaves with the same complaint: the factory ride height. The G8x platform sits too high from the factory, and the aftermarket options are either backordered for months, limited to a single fixed drop, or priced well above what the product justifies. We wanted to offer our customers something better — springs that...

The BMW G80 M3 and G82 M4 are powered by the S58 3.0-litre twin-turbo inline-six — BMW M Division’s most potent six-cylinder production engine. With two mono-scroll turbochargers, a closed-deck block, and forged internals from the factory, the S58 is engineered to handle serious power. But the stock exhaust system, specifically the catalytic converter section immediately downstream of the turbos, is the single biggest restriction holding it back. This guide covers everything about upgrading the downpipe on the G80/G82 platform. The S58 Exhaust Layout Unlike V8 twin-turbo engines with individual downpipes per bank, the S58 inline-six uses two turbochargers feeding...

The BMW S58 twin-turbo inline-six in the G80 M3 and G82 M4 is one of the most tunable engines BMW has ever built. Factory downpipes include restrictive catalytic converters that sit directly downstream of both turbochargers — creating significant backpressure right where exhaust gas velocity is highest. Replacing them with high-flow downpipes is the single most effective bolt-on modification for the S58 platform: reduced turbo lag, more peak power, lower exhaust gas temperatures, and a dramatically more aggressive exhaust note. This guide covers everything you need to know before buying downpipes for your G80 M3 or G82 M4: catless versus...

The BMW S58 3.0-litre twin-turbocharged inline-six is the engine behind the G80 M3, G82 M4, G87 M2, F97 X3 M, and F98 X4 M. It replaced the S55 in 2021 and immediately raised the bar for factory power in the BMW M lineup. The standard M3 and M4 produce 473 HP and 406 lb-ft. The Competition and CSL variants produce 503 HP and 479 lb-ft. The M2 G87 produces 453 HP. BMW's factory calibration on the S58 is among the most conservative in the performance segment. The engine uses forged internals from the factory — forged crankshaft, forged connecting rods,...
