BMW M340i G20 Performance Parts & Upgrades
The BMW M340i xDrive (G20 sedan and G21 Touring) arrived in Australia in 2019, powered by the B58 3.0L turbocharged inline-six with all-wheel drive. The B58 is shared with the M240i, Z4 M40i and Toyota GR Supra, so many engine and cooling parts cross over. This page lists the parts we stock for the M340i, including Dinan intakes, turbo inlets and exhausts, CSF and AMS cooling, AST coilovers, HARDRACE arms and Alcon and Brembo big brake kits.

Popular upgrades for the M340i
- Intake and turbo: aFe and Dinan cold air intakes, carbon turbo inlet pipes, charge pipes and Turbosmart parts.
- Cooling: AMS and CSF heat exchangers, auxiliary radiators and transmission coolers for hot Australian summers and track days.
- Exhaust: Dinan axle-back exhausts and Scorpion systems.
- Suspension: AST coilovers, lowering springs and camber plates, plus HARDRACE and SPL control arms, toe links and bushings.
- Brakes: Alcon and Brembo big brake kits and Paragon 2-piece rotors.
- Engine: ignition coils and spark plugs, and GSC Power-Division camshafts, valves and springs for built B58s.
Choosing the Right Part
- xDrive: every Australian M340i is xDrive (all-wheel drive). Coilovers and springs are often made in separate rear-drive and xDrive versions, so pick the xDrive one.
- Sedan or Touring: most parts fit both the G20 sedan and G21 Touring, but rear suspension and exhaust parts can differ. Check the chassis codes in the title.
- Pre-LCI or LCI: the facelift (LCI) arrived in late 2022. Engine parts carry over, but check any trim or aero part against your build date.
Installation
Have a qualified workshop fit suspension, brake, cooling and engine parts. Get a wheel alignment after any suspension change and bleed and road-test the brakes after brake work. Some engine upgrades need a tune to suit; ask us if you're unsure.
