The Evolution of the M4: From Linear Precision to Turbocharged Force
The BMW M4 hasn’t always existed as its own nameplate. Before 2014, if you wanted a two-door M car, you were looking at the E92 M3 Coupe — naturally aspirated, V8, high-revving. But the introduction of the F82 M4 marked a shift: BMW carved the coupe away from the sedan (now the M3), and moved to a twin-turbocharged inline-six, bringing torque and tuning potential to the forefront.
-
F82 (2014–2020): 3.0L twin-turbo S55 engine, electronically assisted steering, dual-clutch transmission. It was faster, but the critics said it lost some of the raw connection that defined earlier M cars.
-
G82 (2021–present): The current M4 is a weapon. The S58 engine carries over the twin-turbo layout but adds forged internals, upgraded cooling, and a redesigned head. Adaptive suspension, integrated drift analysis, optional xDrive, and a stiffer chassis mean the G82 can lap faster while being daily-drivable.
The G82 BMW M4 isn’t just about numbers — it’s a platform that responds brilliantly to performance upgrades. And this guide is about unlocking that potential.
1. Performance Air Intake: Let It Breathe
Your G82 M4’s stock intake system is engineered for emissions and acoustics, not peak performance. The Mishimoto Performance Air Intake Kit for G8X M3/M4 offers a massive increase in airflow, with dyno-verified gains and improved intake temperatures thanks to a fully enclosed heat shield.

Benefits:
- Cooler intake temps
- Enhanced induction sound
- Improved throttle response
- Ideal for tuned or stock vehicles
This mod doesn’t just add power — it transforms the driving feel, giving your M4 sharper response through the rev range.
2. Exhaust System Upgrade: Sound That Matches the Power
The stock G82 M4 exhaust is subdued — partly due to EU sound restrictions and factory compromise. If you want that iconic M growl without drone or daily discomfort, the AWE Tuning SwitchPath Exhaust for G87 M2 (G8X Fitment) is the solution.
BMW M4 Exhaust Upgrade, Best Performance Exhaust for G82
-
SwitchPath tech lets you toggle between refined and aggressive modes
-
Diamond black tips complete the visual aggression
-
No drone design means perfect daily usability
REVRUNNERS NOTE: This exhaust also reduces back pressure, making it perfect to pair with tuning or downpipes.
3. Custom ECU Tuning: Unleash the S58
Off-the-shelf tunes can work, but a custom ECU tune tailored to your specific setup (intake, exhaust, intercooler, fuel quality) unlocks true performance. The S58 engine is conservatively tuned from factory — with a good tuner, expect:
-
80–100hp gains
-
Improved mid-range torque
-
Sharper throttle response
-
Linear and predictable boost curves

PRO TIP: Always run 98RON fuel and log your pulls. A custom tune adapts to real-world data, not guesswork.
4. Suspension: Confidence Through Corners
Out of the box, the BMW Adaptive M Suspension does a solid job, but for performance driving and confidence at the limit, nothing beats a properly set coilover kit. The KW 2021+ BMW M3 (G80) Sedan/ M4 (G82) Coupe 2WD Coilover Kit V3 brings motorsport tech to the street.

-
Street comfort with track-level control
-
Height-adjustable for perfect stance or corner weight balancing
REVRUNNERS PRO TIP: Match with upgraded control arms and a proper alignment for best results.
5. Intercooler Upgrade: Beat the Heat Soak
The stock intercooler on the G82 M4 is designed to pass emissions, not lap consistently. When intake air temps climb, your ECU pulls timing — and that’s power gone. The Mishimoto Performance Intercooler for G80/G82 solves this.

-
96% increase in core volume
-
36% more surface area
-
Lower intake temps = more consistent power
-
Bolt-on fit with OEM connections
This is the best cooling upgrade for tuned and track-driven M4s — and critical for Australian summers.
Conclusion: Built for the Badge
The G82 M4 may be the most powerful M4 ever built, but it still responds beautifully to the right upgrades. Whether you’re chasing lap times, chasing sound, or chasing the thrill — these mods are about enhancing what’s already there, not masking it.
