Foaming Air Intake Cleaner

Nulon Foaming Air Intake Cleaner is specially formulated to clean the air intake system and combustion chamber without the need to dismantle the engine. The unique additives used in Nulon Foaming Air Intake Cleaner, effectively removes carbon deposits, gum and varnish from the air intake system, restoring your engine to maximum performance.

Over time engines experience build up of sludge, carbon deposits, gum and varnish. These are predominantly found in the throttle body butterfly, intake manifold, plenum chamber and combustion chamber. Using Nulon Foaming Air Intake Cleaner helps clean these areas resulting in improved power and fuel economy. The surface active agent helps to penetrate stubborn carbon deposits while the foam characteristics ensure maximum cleaning effectiveness.

Traditionally, sludge and carbon deposits on the piston crowns could only be cleaned when the engine was dismantled. Nulon Foaming Air Intake Cleaner sprayed into the combustion cylinder onto the piston crown helps to remove accumulated sludge and carbon, restoring the combustion process, enabling optimum fuel burn.

Nulon Foaming Air Intake Cleaner reduces engine pinging (detonation) and restores carburetors and injector systems. It is safe for use in vehicles with fuel injectors, carburetors, catalytic converters and emission control devices.

Nulon Foaming Air Intake cleaner helps restore engine performance and fuel efficiency.

Directions for Use

Shake the can before use, warm up the engine to normal operating temperature and for best results follow through each of the following steps.

1) Throttle plate cleaning:

Turn off engine and disconnect air intake duct from throttle body. Spray sparingly onto the throttle plate, wipe throttle body gently to remove excess liquid. Reconnect the air intake duct to the throttle body.

2) Inlet manifold cleaning:

Disconnect a vacuum hose from the inlet manifold and start the engine. With the engine running at fast idle, spray approximately half of the can through the vacuum line using the spray tube supplied. Then turn OFF the engine and leave to soak for 5 minutes.

If spark plugs are difficult to remove proceed to Step 4:

3) Piston crown cleaning:

While the engine is still turned off, remove all spark plugs. Spray a 2 second burst into each spark plug hole. Leave the engine to stand for 5 minutes. NOTE: Before reinstalling the spark plugs, cover up the spark plug holes with clean unused paper or cloth and crank the engine several times. Reinstall spark plugs.

4) Final cleaning:

Start the engine and disconnect a vacuum hose from the inlet manifold before spraying the rest of the can into the vacuum line while revving the engine. Reinstall the vacuum line and keep the engine running at fast idle until all the remaining cleaner is purged from the exhaust system.

This treatment is recommended for every scheduled service.
