Compressor wheel
Spins to draw in and compress intake air.
Inside the cold-side housing of the turbocharger.
Curved aluminium blades accelerate air outward; the scroll housing turns that speed into pressure.
A fan that squeezes air instead of just moving it.
Chipped blades, oil in the intake or a siren-like noise need a turbo inspection.
Filters follow the vehicle service schedule; ducts and boost hardware are inspected for condition, sealing and operation.
A hose or filter is generally simpler to service than a turbo assembly. Access and diagnosis can dominate cost.
BMW TwinPower Turbo engines pair compact compressor wheels with twin-scroll turbines for quick response.
BMW combustion models; boost hardware applies to turbocharged engines only.
