Power Foam®

Carburetor and Induction-System Cleaner for Two- and Four-Stroke Gasoline Engines

AMSOIL Power Foam® (APF) improves engine performance by removing gum, varnish and carbon deposits that affect power, operation, idle and fuel economy. Power Foam cleans intake valves, intake manifolds and throttle plates to keep the combustion intake system running at peak efficiency. Effective in both two- and four-stroke gasoline engines, Power Foam helps reduce engine ping and keeps carburetors and injector systems operating like new. Power Foam is safe for fuel injectors, catalytic converters and emissions-control devices. It will not damage seals, gaskets, rubber or plastic materials commonly used in gasoline engines.

1. Protect painted surfaces and mass airflow sensors (MAF) from spray.
2. Ensure application is in a well-ventilated area.
3. Run engine to normal operating temperature and remove air cleaner assembly.
4. While engine is running, spray Power Foam directly into throttle body as fast as possible without stalling engine. It is common to have to rev the engine above idle to facilitate this process. It is also common to see white smoke coming out of your exhaust.
5. Once the sound of the engine improves, spray enough Power Foam to choke out the engine. Shut off engine and allow to sit for 10-15 minutes.
6. Replace air cleaner.
7. Restart engine. Repeat application of Power Foam as needed.
8. In four-stroke engines, an oil change is recommended after treatment. In extreme cases, disassemble carburetor and soak parts.

Avoid contact with hoses and exterior plastic components. To prevent the dissolving of paint, do not overspray. Clean any overspray immediately to prevent unintentional component damage. AMSOIL Power Foam® is not recommended for use in diesel engines, GDI engines or as a general-purpose degreaser.
