Genuine NGK SIFR6B7G (94675) Laser Iridium Spark Plug — Specifications, Features & Applications

The NGK SIFR6B7G, identified by stock number 94675, is a premium Laser Iridium spark plug designed for modern petrol engines that require precise ignition, dependable performance, and extended service life. Part of NGK’s Laser Iridium lineup, this plug features a fine-wire iridium center electrode paired with a platinum-tipped ground electrode. This dual precious-metal construction helps minimize electrode wear and maintain consistent ignition performance over extended operating intervals.

Unlike conventional nickel spark plugs, the SIFR6B7G is engineered to provide reliable spark formation with a durable electrode design that supports smooth engine operation, dependable starting, and efficient combustion. It is used in selected Haval and Changan petrol-engine applications, including certain turbocharged models. However, exact compatibility depends on the vehicle’s engine code, model year, and original equipment specifications.

Technical Specifications

What Makes This Plug Different

Fine-wire iridium for reliable ignition. The SIFR6B7G uses a fine-wire iridium center electrode designed to promote high ignitability. Its concentrated spark area helps support dependable ignition, particularly in modern engines with demanding combustion requirements.

Platinum-tipped ground electrode for extended durability. The platinum tip on the ground electrode complements the iridium center electrode. Both precious metals resist wear, helping maintain the intended electrode geometry and spark gap for longer than many conventional nickel-alloy designs.

Consistent combustion and smoother operation. A correctly specified Laser Iridium spark plug helps deliver reliable ignition across repeated engine cycles. When the ignition system and engine are properly maintained, this can contribute to smooth idling, dependable starts, and responsive acceleration.

Designed for modern petrol engines. The SIFR6B7G is found in selected turbocharged and other petrol-engine applications. Its electrode construction is suited to the specific ignition requirements of the engines for which it is recommended, making correct application matching especially important.

Helps maintain ignition performance over time. Electrode erosion can gradually change the spark gap and affect ignition reliability. The iridium-and-platinum construction helps resist this wear, supporting consistent operation throughout the manufacturer’s recommended replacement interval.

Corrosion-resistant shell protection. NGK spark plugs feature protective shell finishes designed to help resist corrosion and make removal easier during routine servicing. Correct installation torque remains essential to prevent thread damage and ensure a reliable seal.

Factory-specified spark gap and heat range. This plug has a nominal gap of 0.7 mm and an NGK heat range of 6. The correct gap and heat range are important for reliable ignition and appropriate heat dissipation. Always follow the vehicle manufacturer’s service specifications and avoid adjusting the fine-wire electrodes unless the manufacturer explicitly permits it.

Where This Plug Fits

The NGK SIFR6B7G (94675) is listed for selected Haval and Changan petrol vehicles. Depending on the market, engine variant, and production year, applications may include:

• Haval H6 — selected 1.3L, 1.5L, and 2.0L petrol-engine variants, subject to engine-code verification.
• Haval H8 — selected 2.0L turbocharged petrol-engine variants.
• Haval H9 — selected 2.0L turbocharged petrol-engine variants.
• Changan CS75 — selected 1.5L, 1.8L, and 2.0L petrol-engine variants listed in NGK catalogues.

These examples are not a guarantee of fitment for every vehicle carrying the same model name. Engine specifications and recommended spark plugs can vary by production year, market, and engine code. Confirm compatibility through the official NGK application catalogue or the vehicle manufacturer’s parts information before ordering.

Why Choose the Genuine NGK SIFR6B7G?

The NGK SIFR6B7G combines a fine-wire iridium center electrode with a platinum-tipped ground electrode to provide a durable ignition solution for compatible engines. Its design prioritizes reliable spark formation, resistance to electrode wear, and consistent performance throughout the recommended service interval.

For owners of compatible Haval and Changan vehicles, choosing the correct genuine NGK plug helps preserve the engine’s intended ignition characteristics and supports dependable everyday operation. It is particularly important to use the specified plug in turbocharged engines, where the correct electrode design, gap, and heat range are essential to the manufacturer’s ignition requirements.

Before purchasing, compare the part number on your existing spark plug with SIFR6B7G (94675), check your vehicle’s engine code, and verify the recommended plug in the owner’s manual or an authoritative parts catalogue. This simple check helps avoid incorrect fitment and ensures that the replacement matches your engine’s requirements.
