(12 pack) GUNK GDI Intake Valve & Carbon Deposit Cleaner with 10 ft MaxReach Straw, 11 oz — One-Person Application, PEA Formula for Turbo, GDI & PFI Engines, Cars, SUVs & Trucks

Carbon deposits are the silent performance killer in GDI engines. Over time, they coat intake valves, choking off airflow, roughening idle, and stealing horsepower. The fix used to mean a shop visit or a two-person job under the hood. Not anymore. GUNK GDI Intake Valve Cleaner is the only valve cleaner built for one-person application. The 10 ft. MaxReach Straw™ reaches from the air intake to the driver’s seat, so you can rev the engine and spray simultaneously — no assistant, no mechanic, no appointment. The professional-strength PEA formula dissolves 77% of carbon deposits in under one hour. Power and torque come back. Idle smooths out. Throttle response sharpens. It’s safe for oxygen sensors and catalytic converters, and it works on turbo, supercharged, twin-turbo, GDI, and PFI engines in compact cars, SUVs, and trucks. Use it every 10,000 miles or with every oil change. One can. One person. Professional results. Scan the included QR code for a step-by-step application video.

• Do It Yourself — No Helper Needed: The 10 ft. MaxReach Straw™ lets one person apply the cleaner while seated behind the wheel. No second person, no shop visit. Just sit, rev, and spray. GUNK is the only intake valve cleaner designed for true one-person use.
• Dissolves 77% of Carbon Deposits in Under 1 Hour: The professional-strength PEA (Polyether Amine) formula breaks down baked-on carbon buildup on intake valves, restoring lost horsepower and torque.
