BOSCH Nickel Super Plus Spark Plug, Spanner Size 16, Article Number: 0242229654 / FLR8LDCU+

BOSCH Nickel Super Plus Spark Plug – FLR8LDCU+ (Article No.: 0242229654)

The BOŚCH Nickel Super Plus Spark Plug is a high‑performance ignition component engineered to deliver reliable spark, superior combustion efficiency, and extended durability across a wide range of gasoline engines. Designed with advanced metallurgy and precision engineering, this plug offers exceptional heat tolerance and consistent performance even under demanding operating conditions.

Key Features & Technical Highlights

• Nickel‑Coated Electrode: The electrode is plated with a nickel alloy that resists corrosion, oxidation, and wear. This coating ensures a stable spark gap over the plug’s service life, reducing the need for frequent replacements.
• Optimized Heat Range: Engineered to maintain an optimal temperature profile, the plug balances heat dissipation with combustion efficiency. It prevents overheating in high‑performance engines while retaining enough heat to avoid fouling in low‑speed or cold‑start conditions.
• Precision Spark Gap: The spark gap is manufactured to exact tolerances, guaranteeing consistent ignition timing and reducing misfires. This precision contributes to smoother engine operation and improved fuel economy.
• Durable Insulator: Made from high‑grade ceramic material, the insulator withstands thermal cycling and mechanical stress, ensuring long-term reliability even in engines with aggressive combustion cycles.
• Spanner Size 16mm: The plug’s threaded shank is designed for a standard 16 mm spanner, facilitating easy installation and removal without specialized tools.

Compatibility & Vehicle Applications

The FLR8LDCU+ spark plug is engineered to fit a broad spectrum of gasoline engines from various manufacturers. Its versatile design makes it suitable for:

• Audi, VW, Skoda, Seat, and Škoda models – including the A4 Avant (B6/B7), Passat (3B3/3B6), and other inline‑four engines.
• Opel, Vauxhall, and Chevrolet – compatible with a range of small to mid‑size gasoline engines found in models such as the Astra, Corsa, Meriva, and Zafira.
• Fiat, Alfa Romeo, and Lancia – suitable for many front‑engine, front‑wheel‑drive vehicles that use a standard spark plug configuration.
• Daewoo, Daihatsu, and Dacia – fits engines in compact cars and light commercial vehicles.
• Saab, Skoda, and Volvo – compatible with older and newer models that use the same spark plug specifications.

Because of its universal design, the FLR8LDCU+ can be used as a direct OEM replacement or an aftermarket upgrade in most gasoline engines that require a 24 mm diameter, 16 mm spanner size spark plug. Always verify the specific engine requirements before installation.

Installation & Maintenance Guidelines

1. Preparation: Ensure the engine is cool and disconnect the battery to prevent accidental sparks during removal.
2. Removal: Use a 16 mm spanner or spark plug socket to loosen the existing plug. Rotate counter‑clockwise until it comes free.
3. Inspection: Check the old plug for signs of wear, carbon buildup, or damage. This can indicate engine health issues that may need addressing.
4. Installation: Align the new FLR8LDCU+ with the spark plug boot and hand‑tighten it to avoid cross‑threading. Then use a torque wrench set to the manufacturer’s recommended torque (typically around 13–15 Nm for most gasoline engines).
5. Final Check: Reconnect the battery, start the engine, and listen for smooth operation. A consistent idle and absence of misfires confirm proper installation.

Performance Benefits

• Enhanced Combustion Efficiency: The nickel coating reduces spark energy loss, leading to more complete fuel combustion and better throttle response.
• Improved Fuel Economy: A reliable spark reduces wasted fuel, contributing to lower consumption over the plug’s lifespan.
• Reduced Emissions: Efficient combustion results in fewer unburnt hydrocarbons, helping vehicles meet stricter emission standards.
• Longer Service Life: The robust construction and corrosion‑resistant coating extend the interval between replacements, offering cost savings for owners.
