SMA ProQor Intake Valve & Combustion Chamber Cleaner 16 oz Kit — PEA Carbon Cleaner for GDI/PFI/TBI with Hose & Shop Towel

Berryman 2611 is a professional-strength intake valve and combustion chamber spray that uses PEA chemistry and a direct-induction application to dissolve carbon deposits in gasoline engines.

This kit combines a 16 oz Berryman 2611 can with application hoses and adapters plus an SMA ProQor reusable shop towel, giving technicians and DIYers a ready-to-use solution for removing stubborn carbon from intake ports, valves, and combustion chambers. Formulated for modern fuel-injected gasoline engines — including GDI (gasoline direct injection), PFI (port fuel injection), and TBI (throttle body injection) systems — the cleaner is applied while the engine runs so the active ingredients reach the areas where deposits form. The PEA (polyetheramine) base targets heavy varnish and carbon without harming oxygen sensors or catalytic components when used as directed.

How does this cleaner reach intake valves and combustion chambers?

The Berryman 2611 is designed for direct-induction application while the engine is idling, allowing the spray to flow through the intake tract to targeted areas. The kit’s hose and adapter set fits a wide range of intake ports so the chemical contacts deposits on valves and inside the combustion chamber more effectively than fuel-only treatments.

• Application hose and adapters included for flexible access.
• Applied with engine running to carry PEA deep into ports and chambers.
• Works on GDI, PFI, and TBI systems with proper procedure.

What makes PEA-based cleaning effective for carbon removal?

Polyetheramine (PEA) is a professional-grade solvent known for breaking down baked-on carbon and varnish without aggressive scrubbing. It chemically loosens deposits so they can be expelled through the intake or burned out in the combustion process, improving airflow and combustion consistency.

• Targets hard carbon and lacquer-like deposits that fuel additives often miss.
• Helps restore smoother idle, throttle response, and acceleration.
• Formulated to be safe for sensors and catalytic converters when used correctly.

Can I use this on my engine type and what results should I expect?

This cleaner is suitable for gasoline engines with fuel injection systems — GDI, PFI, and TBI — when applied per the instructions by a qualified technician or knowledgeable DIYer. Typical outcomes include reduced intake restrictions and improved drivability, though results vary with the age and severity of deposits.

• Recommended for engines showing rough idle, hesitation, or reduced throttle response.
• Not a guaranteed cure for mechanical damage; best for carbon-related performance loss.
• Follow manufacturer guidance for frequency and proper application to avoid misuse.

What’s included in the kit and how does the SMA ProQor towel help?

The package delivers a full induction-cleaning setup: one 16 oz can of Berryman 2611, hose and adapter hardware for induction port access, and a durable SMA ProQor shop towel. The towel helps keep hands, fittings, and work areas clean during the procedure, making the process neater and safer.

• One 16 oz Berryman 2611 can with application hose kit (MPN 2611).
• Adapters to fit a variety of intake configurations and injection setups.
• SMA ProQor reusable towel for wiping spills, protecting surfaces, and cleaning tools.

Who is this for: This product is aimed at professional mechanics, service shops, and experienced DIY enthusiasts who perform induction service and engine maintenance. It’s appropriate for owners of gasoline vehicles experiencing carbon-related symptoms who want a more thorough, PEA-based cleaning than routine fuel-injector additives provide. If you’re unfamiliar with induction cleaning procedures or vehicle-specific requirements, consult a service manual or a trained technician before use to ensure compatibility and safe application.
