OE Fine Wire Iridium Product Line Details
The Bosch OE Fine Wire Iridium line focuses on delivering spark plugs with fine wire iridium center electrodes, enhancing ignition efficiency and longevity. The FR7SI30 spark plug benefits from this technology by combining platinum-iridium tips with a nickel-yttrium ground electrode, providing stable spark performance and extended service life in Mitsubishi Mirage vehicles.
Technical Description and Specifications
The FR7SI30 spark plug features a 6000 ohm resistor to reduce electrical noise and protect ignition components. Its single ground electrode with a standard design ensures consistent spark generation. The ceramic insulator with a projected type improves voltage insulation and heat dissipation. The spark plug’s 14 mm thread diameter and 26.5 mm reach are designed to fit Mitsubishi Mirage and Mirage G4 engines precisely. The flat seat type ensures a secure and proper seal within the combustion chamber.
Applications and Problem Solving
- Restores proper ignition timing and spark delivery in Mitsubishi Mirage and Mirage G4
- Reduces misfires caused by worn or damaged spark plugs
- Improves fuel efficiency by ensuring complete combustion
- Minimizes engine hesitation and rough idling
- Prevents ignition system interference with resistor design
Installation Notes and Tips
- Use a 16 mm socket wrench for installation or removal
- Verify the pre-gap of 1.1 mm before installation to ensure optimal spark
- Apply anti-seize compound on threads if recommended by vehicle manufacturer
- Torque spark plug to manufacturer specifications to avoid damage
- Replace spark plugs in sets of three as per Mitsubishi Mirage maintenance guidelines
Quality Assurance and Warranty
Bosch FR7SI30 spark plugs are manufactured to meet OEM standards for fit, form, and function. The use of premium materials such as platinum-iridium and nickel-yttrium ensures durability and consistent performance. Bosch provides quality assurance through rigorous testing, although specific warranty details should be confirmed with the vehicle or part supplier.
