Sea Foam Upper Engine Spray Cleaner SS14 14 oz Pack of 2 — GDI-safe intake & valve cleaner with light lubricant

Sea Foam Spray SS14 is a concentrated upper-engine cleaner and lubricant designed to dissolve intake and combustion deposits by spraying through the air intake or carburetor throat.

Sea Foam Spray targets the upper areas of gasoline engines where tank-additive cleaners cannot reach. It dissolves gum, varnish and carbon buildup on intake runners, valves and combustion chamber surfaces while leaving a light lubricating film on throttle plates and upper cylinder components. Safe for oxygen sensors and coated parts, this aerosol offers a direct application method for Gasoline Direct Injection (GDI) engines and other systems that accumulate stubborn deposits.

How does Sea Foam Spray remove deposits from intake ports and valves?

The aerosol carries solvent and detergent agents directly into intake runners and valves, softening and breaking down baked-on residues so they can be removed or burned away. Repeated short sprays during idle or controlled throttle operation dislodge buildup without removing protective coatings.

• Applied through the air intake or carburetor throat for targeted cleaning.
• Softens carbon, varnish and gum on valve faces and intake passages.
• Can be used while the engine is warmed, under manufacturer-recommended conditions.

Will using this spray harm oxygen sensors or coated engine parts?

Sea Foam Spray is formulated to be safe for oxygen sensors and common engine coatings when used as directed. It evaporates cleanly and leaves minimal residue, reducing risk to emissions components compared with harsh aftermarket solvents.

• Designed to be sensor-safe when following application instructions.
• Suitable for coated surfaces—avoids stripping protective finishes.
• Evaporates without heavy deposits, lowering contamination risk.

How does this product help with GDI engines and why is upper-intake cleaning important?

GDI engines inject fuel directly into the cylinder, so injectors don’t wash intake valves—this lets deposits build up faster. Sea Foam Spray reaches those upper intake areas to remove deposits that reduce airflow, affect metering and impair throttle response.

• Targets intake valves and runners that tank additives can’t reach in GDI systems.
• Improves airflow and throttle response by reducing restrictive buildup.
• Can extend component life by removing abrasive carbon layers.

How should I apply Sea Foam Spray safely for best results?

Follow the product instructions and vehicle manufacturer recommendations: warm the engine, use short bursts, and avoid over-application. Work in a well-ventilated area and consider professional service for heavily soiled systems or complex intake designs.

• Warm the engine to operating temperature before light, controlled applications.
• Use brief spray bursts through the air intake or carb throat—do not flood the system.
• Wear protective gloves and eye protection; ensure good ventilation.

Who is this for: Sea Foam Spray SS14 is intended for car owners, mechanics and restoration enthusiasts who need a targeted way to remove upper-intake and valve deposits—particularly useful on GDI engines, vehicles with rough idle or throttle hesitation, and machines in storage requiring protective lubrication. This pack of two 14 oz cans supplies enough product for multiple cleanings or for servicing several vehicles, giving you a practical option for routine maintenance and deposit control.
