Wynns Direct Injection Valve Cleaner is a 500ml treatment for the carbon that builds up on the inlet valves of direct-injection engines. It cleans valve stems and seats, the combustion chamber and the piston crowns, bringing back proper airflow into the engine and smoother, more correct running.

Good to know

• Why do direct-injection engines need it? On direct-injection-only engines the fuel is sprayed straight into the cylinder, so it doesn't wash over the inlet valves and carbon builds up on them, choking the airflow.
• What symptoms point to dirty valves? Rough idle, hesitation, misfires and lost power on a higher-mileage direct-injection engine; read any fault codes first to rule out coils or injectors.
• Will it clear very heavy carbon? Light and moderate build-up, yes; valves caked solid usually need walnut blasting or a head off, which this can't replace.

Which one?

For a foam that cleans the whole intake including the throttle body, turbo and EGR, the Wynns Intake System Cleaner HI-Power Foam (29979); for petrol EGR and airflow sensor cleaning, the Wynns Petrol EGR Cleaner – 150ml (29881).
