Bosch FGR4NQE04 - Spark Plugs Nickel - 1 piece

Bosch FGR4NQE04 – Nickel Spark Plug (Single)

The Bosch FGR4NQE04 is a high‑performance nickel spark plug designed for modern internal combustion engines that demand precise ignition timing and reliable performance. This single unit is engineered to deliver consistent spark energy, ensuring optimal combustion efficiency across a wide range of operating conditions.

Key Technical Specifications

• Model Number: FGR4NQE04 (also referenced as 0242250518 in OEM catalogs)
• Thread Size: M14 x 1.25 mm – a standard size for many high‑performance engines.
• Heat Range: Medium to medium‑high, suitable for engines with moderate to high compression ratios.
• Material Composition: Nickel alloy coating on the electrode and insulator, providing excellent resistance to heat and corrosion.
• Operating Temperature: Up to 1,200 °C (2,192 °F) without degradation of performance.

Design Features That Enhance Performance

The FGR4NQE04 incorporates several design elements that set it apart from standard spark plugs:

• Nickel Coating: The nickel layer on the electrode reduces wear and extends service life, especially in high‑temperature environments.
• Optimized Electrode Gap: A precisely engineered gap ensures a strong spark at low voltages while maintaining reliability under load.
• Robust Insulator: Made from advanced ceramic material, the insulator withstands thermal cycling and mechanical shock.
• Threaded Design: The M14 x 1.25 mm thread provides a secure fit in cylinder heads, minimizing the risk of loosening during engine operation.

Applications and Compatibility

This spark plug is widely used in high‑performance vehicles that require durable ignition components. It is especially popular among enthusiasts who modify engines for increased power output. Common applications include:

• Porsche 911 (997) Convertible, Cabriolet, Targa models: The FGR4NQE04 fits the 3.6‑ and 3.8‑liter flat‑six engines found in these iconic sports cars.
• Other high‑compression engines: Any engine that benefits from a nickel‑coated electrode for improved spark consistency.
• Performance tuning setups: Engines with forced induction or aftermarket ignition systems often select this plug to match their upgraded performance profile.

Installation Guidelines

Proper installation is critical to achieving the full benefits of the FGR4NQE04. Follow these steps for optimal results:

1. Prepare the Cylinder Head: Clean the spark plug seat and remove any debris or old gasket material.
2. Apply Anti‑Seize Compound (Optional): A thin layer can help prevent galling during installation, though it is not mandatory for this model.
3. Screw in the Plug: Hand‑tighten until snug, then use a torque wrench to achieve the manufacturer’s recommended torque setting (typically around 30–35 Nm).
4. Check the Gap: Verify that the electrode gap matches the specified value for your engine. Adjust if necessary using a spark plug gapping tool.
5. Reconnect the Ignition Coil: Ensure all connections are secure and free of corrosion before starting the engine.

Maintenance Tips

While the FGR4NQE04 is designed for longevity, regular maintenance can further extend its life:

• Inspect Periodically: Check for signs of wear or damage on the electrode and insulator during routine service intervals.
• Replace When Needed: If you notice misfires, rough idling, or a noticeable drop in performance, consider replacing the plug sooner than the typical 100,000‑mile interval.
• Keep the Engine Cool: Excessive heat can accelerate wear; ensure your cooling system is functioning properly to maintain optimal operating temperatures.
