Fits Most 4-Stroke Gasoline Engines, Including Turbocharged Models

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. This advanced formula effectively dissolves and removes stubborn deposits and contaminants that accumulate over time, ensuring smooth operation of moving parts and optimal engine performance. It is particularly well-suited for modern Gasoline Direct Injection (GDI) engines, where intake valves are prone to buildup.

Regular use of this cleaner helps keep the entire intake system in excellent working condition, reducing the risk of costly repairs and maintaining fuel efficiency. Safe for use with catalytic converters, Exhaust Gas Recirculation (EGR) systems, and Gasoline Particulate Filters (GPF), it is compatible with virtually all 4-stroke gasoline engines, whether naturally aspirated or turbocharged.

Key Features:

This throttle valve cleaner offers a range of benefits that make it an essential maintenance product for gasoline engines:

• Effectively dissolves and removes deposits in the intake manifold and throttle body
• Restores normal function of moving parts for smoother throttle response
• Ideal for cleaning intake valves on modern GDI engines
• Safe for use with catalytic converters, EGR valves, and GPF systems
• Can be applied without dismantling the intake system
• Prevents buildup that can lead to reduced engine performance and increased emissions
• One 400 ml can is sufficient for a single application
• Recommended preventive use every 12 months or 10,000 miles
• Rapid and simple application process using the supplied spray probe
• Helps reduce repair costs by maintaining intake system cleanliness

Construction & Design:

The cleaner is formulated from a blend of powerful cleaning agents specifically engineered to target carbon deposits and other contaminants common in gasoline engine intake systems. Packaged in a 400 ml aerosol can, it includes a spray probe designed for precise application directly into the throttle housing. The spray head is pre-assembled for transport safety and must be replaced with the supplied spray probe before use to ensure optimal delivery.

The formula is carefully balanced to be safe on sensitive engine components and emissions control devices, preventing damage while providing thorough cleaning. Its design allows for effective cleaning without the need to dismantle the intake manifold or throttle body, saving time and effort during maintenance.

Installation & Fitment:

The Liqui Moly Pro-Line Throttle Valve Cleaner is suitable for all 4-stroke gasoline engines, including those equipped with turbochargers. It is compatible with a wide range of makes and models, making it a versatile choice for most gasoline-powered vehicles.

To apply, attach the supplied spray probe to the can and access the intake tract 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 coverage. If engine speed fluctuates excessively, pause spraying until it stabilizes. Avoid contact with the air mass sensor and painted surfaces. After treatment, allow the engine to run at 2000 rpm for at least 20 seconds to clear any residual fluid. If heavy deposits are present, a second can may be used for improved results.

What's Included:

• One 400 ml can of Liqui Moly Pro-Line Throttle Valve Cleaner
• Spray probe for precise application

Ideal For:

This product is ideal for automotive technicians, enthusiasts, and everyday drivers who want to maintain optimal engine performance and longevity. It is especially beneficial for vehicles with modern GDI engines prone to intake valve deposits, as well as those seeking to prevent costly repairs related to clogged throttle bodies and intake manifolds. Regular preventive use helps maintain fuel efficiency, reduce emissions, and ensure smooth throttle response.
