Berryman Intake Valve & Combustion Chamber Cleaner – 16 oz Aerosol, PEA Formula for GDI & PFI Engines

Engine deposits on intake components and in combustion chambers reduce efficiency and can affect throttle response, emissions, and fuel economy. Berryman’s 2611 Intake Valve and Combustion Chamber Cleaner is formulated for use in all fuel-injected gasoline engines — including port-fuel-injected (PFI), throttle-body-injected (TBI), and gasoline direct injection (GDI) systems — and uses polyetheramine (PEA) to target stubborn carbon buildup while remaining safe for catalytic converters and oxygen sensors when used as directed.

What does this cleaner remove from modern engines?

Berryman 2611 targets carbonized deposits that form on intake valves, in combustion chambers, and on intake ports. The PEA chemistry breaks down heavy varnish and soot that simple detergents can’t reach, helping restore the internal surfaces closer to their original condition.

• Dissolves baked-on carbon on intake valves and ports
• Loosens combustion chamber deposits and lead-free fuel residues
• Removes varnish, gum, and oily buildup from fuel-injection passages
• Effective on deposits that impair air/fuel flow in GDI systems

How do I apply the 16-ounce aerosol in fuel-injected vehicles?

The aerosol allows controlled application to the intake system or during a professional induction service. Follow manufacturer directions, avoid diesel engines, and perform the procedure in a well-ventilated area, using proper safety equipment.

• Shake can well and follow label dosage and access instructions
• Apply through the throttle body or intake while engine is running as directed
• Allow sufficient soak time for PEA to penetrate tough carbon
• Observe safety guidance: gloves, eye protection, and ventilation

Will using this product harm sensors or the catalytic converter?

Berryman 2611 is formulated to be safe on catalytic converters and oxygen sensors when used according to the product instructions. It avoids harsh additives known to damage emissions controls, but correct application and dosing are critical to prevent unintended contamination.

• Safe for catalytic converters and O2 sensors when used as directed
• Not formulated for diesel engines — restrict use to gasoline engines only
• Follow vehicle and product instructions to avoid over-application

How often should intake and combustion chamber cleaning be performed?

Cleaning frequency depends on driving conditions, fuel quality, and whether the engine is GDI or PFI. Routine inspections every 30,000–60,000 miles are common, with targeted cleaning whenever symptoms like rough idle, reduced power, or decreased fuel economy appear.

• Inspect intake and combustion areas during regular service intervals
• Consider cleaning sooner for stop-and-go, short-trip, or dusty driving
• Use product as part of preventive maintenance on GDI engines prone to buildup

This formula represents Berryman’s commitment to long-standing quality, reliability, and environmental responsibility. The product is not for diesel engines and should be used following all label directions to ensure safety and compatibility with emissions systems. If in doubt, consult a technician for professional application.

Who is this for? Vehicle owners, do-it-yourself mechanics, and professional technicians who service gasoline fuel-injected engines — especially those with GDI systems — and need a PEA-based aerosol cleaner to remove carbon deposits from intake valves and combustion chambers while protecting emissions components.
