Wynn's Petrol Injector Cleaner - Restores Spray Pattern - Prevents Deposits, Improves Combustion & Cold Start - Reduces Fuel Consumption & Emissions - 325ml
View Deal on:
View Deal
Main Highlights
- THOROUGH CLEANING OF INJECTORS AND FUEL SYSTEM COMPONENTS: Effectively eliminates existing deposits in injectors and the fuel pump while ensuring that these vital engine components remain clean over time. This advanced cleaning action not only helps restore the optimal spray pattern of the injectors but also contributes to smoother engine performance. Built-up residues in the injectors, intake manifold, and combustion chamber are among the most common causes of reduced engine efficiency and increased emissions.
- PREVENTS DEPOSIT FORMATION AND IMPROVES ENGINE DURABILITY: Acts as a powerful preventative treatment that stops the formation of harmful carbon deposits on intake valves, inside the manifold, and in the combustion chamber. These deposits can severely impact engine performance, leading to knocking, poor fuel economy, and increased exhaust emissions. By creating a protective environment within the fuel system, the product ensures long-term cleanliness and consistent fuel delivery. It is compatible with both leaded and unleaded petrol, making it versatile and reliable across a wide range of petrol engines.
- SMOOTHER ACCELERATION, COLD START SUPPORT, AND STABLE IDLING: Provides a noticeable improvement in engine operation by preventing irregular idling and hesitation during acceleration. It is particularly effective in helping engines start more easily in cold conditions, reducing the strain typically associated with cold starts. The formula is designed to support steady and smooth acceleration by addressing jerking, knocking, and auto-ignition issues. These issues often arise from an unbalanced air-fuel mixture caused by dirty injectors or valve deposits.
- LUBRICATION OF CRITICAL ENGINE PARTS FOR OPTIMAL COMBUSTION: This lubrication plays a significant role in reducing friction and wear, especially in high-stress areas that experience intense pressure and heat. By improving the internal lubrication of the engines fuel system, it helps to enhance combustion efficiency and reduce fuel consumption. Well-lubricated components operate more smoothly and are less prone to long-term damage, which supports extended engine life and consistent performance. The result is a more efficient engine that consumes less fuel and emits fewer pollutants.
- PROTECTION AGAINST RUST, CORROSION, AND MOISTURE ACCUMULATION: Offers comprehensive protection for the entire fuel system by preventing rust and corrosion, especially in metallic components exposed to fluctuating temperatures and humidity. The product absorbs condensation and moisture that may accumulate in the fuel tank or lines, helping to avoid water-related damage that can compromise engine performance. This protective effect is especially valuable in environments where fuel quality may vary or where engines are not used frequently.

- PROTECTS CRUCIAL ENGINE COMPONENTS TURBO, EGR VALVE & CATALYTIC CONVERTER: Keeping key engine components clean is essential for preventing performance issues and costly repairs. This powerful cleaner helps maintain the efficiency of the turbocharger, exhaust gas recirculation (EGR) valve, and catalytic converter by reducing carbon buildup and prevents harmful deposits from forming. By keeping these components free of obstructions, it allows for optimal airflow and exhaust processing, reducing the risk of blockages and malfunctions.
- PREVENTS STARTING ISSUES & ENSURES SMOOTH IGNITION: A dirty fuel system can lead to difficult engine starts, misfires, and rough idling. This advanced cleaner eliminates the contaminants that interfere with proper fuel delivery, ensuring a more efficient and reliable ignition process. By keeping fuel injectors, intake valves, and combustion chambers clean, it ensures proper fuel atomisation and smooth engine start-up, even in cold weather conditions. Regular use of this cleaner helps prevent common fuel-related issues, reducing the chances of stalling, hesitation, or power loss while driving.
- PEA-BASED FORMULA FOR MAXIMUM CLEANING POWER: Formulated with Polyetheramine (PEA), this fuel system cleaner offers superior cleaning performance by breaking down stubborn deposits that traditional cleaners struggle to remove. PEA effectively dissolves carbon, varnish, and other contaminants that accumulate in the fuel system, ensuring a thorough cleaning action. This advanced formula works quickly to restore optimal fuel injector spray patterns, improving combustion efficiency and reducing harmful emissions. Unlike conventional additives, this high-strength cleaner provides long-lasting protection, keeping the fuel system clean and functioning at peak performance for extended periods.
