Liqui Moly Pro-Line Throttle Valve Cleaner
Fits Most Models – All 4-Stroke Gasoline Engines
20210
Overview:
The Liqui Moly Pro-Line Throttle Valve Cleaner is a specialized cleaning solution designed to maintain and restore the intake manifold and throttle body of gasoline engines. Formulated with a powerful blend of cleaning agents, it effectively dissolves and removes deposits, contaminants, and carbon buildup that can impair engine performance. This product is ideal for both naturally aspirated and turbocharged 4-stroke gasoline engines, including modern Gasoline Direct Injection (GDI) systems.
Regular use of this cleaner helps ensure the smooth operation of moving parts within the intake system, reduces the risk of costly repairs, and maintains optimal engine responsiveness. It is safe for use with catalytic converters, Exhaust Gas Recirculation (EGR) valves, and Gasoline Particulate Filters (GPF), making it a reliable choice for maintaining emissions control components.
Key Features:
Liqui Moly Pro-Line Throttle Valve Cleaner offers a comprehensive cleaning solution that supports engine efficiency and longevity. Key features include:
- Effectively dissolves and removes deposits and contaminants from throttle bodies and intake manifolds
- Restores normal function of moving parts within the intake system
- Specifically formulated for gasoline engines, including modern GDI engines
- Safe for use with catalytic converters, EGR valves, and Gasoline Particulate Filters (GPF)
- Enables cleaning without dismantling intake components
- Prevents buildup that can cause rough idling, hesitation, and reduced fuel economy
- One 400 ml can is sufficient for a single application
- Recommended preventive use every 12 months or 10,000 miles to maintain intake system health
- Rapid and simple application process with spray probe for precise delivery
Construction & Design:
The cleaner is housed in a 400 ml aerosol can equipped with a spray probe designed for targeted application inside the intake tract. The formulation is engineered to be safe on sensitive engine components and emissions systems, ensuring no damage to catalytic converters, EGR valves, or particulate filters. The spray probe allows for controlled, even distribution of the cleaning fluid, maximizing contact with deposits while minimizing overspray on sensors or painted surfaces.
The product’s chemical composition is optimized to break down carbon and other stubborn residues without requiring disassembly of the intake system, simplifying maintenance and reducing labor time.
Installation & Fitment:
This throttle valve cleaner fits most 4-stroke gasoline engines, including those with or without turbochargers. To apply, attach the supplied spray probe to the can and gain access by removing the hose or pipe immediately before the throttle housing. The engine must be running during application, maintaining a minimum speed of 2000 rpm.
Spray the cleaner in short intervals of 2-3 seconds while moving the nozzle back and forth across the intake opening to ensure thorough treatment. If engine speed fluctuates excessively, pause spraying until stable. Avoid contact with the air mass sensor and painted surfaces. For heavy deposits, a second can may be used. After cleaning, keep the engine running at 2000 rpm for at least 20 seconds to clear any residual fluid, then erase any stored fault codes.
What's Included:
- One 400 ml can of Liqui Moly Pro-Line Throttle Valve Cleaner
- Pre-attached spray probe for precise application
Ideal For:
This product is ideal for automotive enthusiasts, professional mechanics, and everyday drivers who want to maintain engine performance and reduce repair costs. It is especially beneficial for vehicles experiencing rough idling, hesitation, or reduced fuel efficiency due to intake system deposits. Regular preventive use helps keep intake valves, throttle bodies, and intake manifolds clean and functioning optimally.
