Bosch FR7NII35U - Spark Plugs Double Platinum - 1 piece

Bosch FR7NII35U – Double Platinum Spark Plug

The Bosch FR7NII35U is a premium double platinum spark plug, engineered to deliver exceptional ignition performance and long‑term reliability in modern gasoline engines. Designed for high‑efficiency vehicles, this single‑piece component offers superior heat dissipation, precise spark timing, and extended life compared with conventional copper plugs.

Key Features & Benefits

• Double Platinum Coating: The dual layers of platinum on the electrode enhance conductivity and resist wear, ensuring a consistent spark over thousands of miles.
• Optimized Heat Range: Engineered for moderate to high‑temperature engines, it maintains optimal combustion temperatures without overheating.
• Improved Fuel Efficiency: Precise ignition timing reduces fuel consumption and emissions by promoting complete combustion.
• Extended Service Life: Platinum’s resistance to corrosion and erosion extends the plug’s lifespan, reducing maintenance frequency.
• Consistent Performance: Maintains spark intensity across a wide range of operating conditions, from cold starts to high‑RPM driving.

Technical Specifications

Installation & Maintenance Tips

1. Check Clearance: Verify that the spark plug gap matches the manufacturer’s specification for your engine. Adjust with a feeler gauge if necessary.
2. Use Proper Torque: Tighten to the recommended torque setting (typically 100–120 in‑lb) to avoid over‑ or under‑tightening, which can damage the seat or compromise sealing.
3. Inspect for Wear: After a set of miles, inspect the electrode for signs of erosion. Replace if the gap widens beyond spec.
4. Avoid Cross‑Contamination: Keep the plug clean from oil or coolant residues before installation to ensure optimal spark delivery.
