FAQs

What vehicles is the NGK SILZKFR8D7S / 95875 compatible with?

This spark plug is specifically designed for various Mercedes models including A Class, B Class, C Class, E Class, GLA Class, and S Class. It replaces Mercedes part numbers 0041596503, 0041596803, 0041597203, 0041597503, A0041596503, A0041596803, A0041597203, and A0041597503. Always verify compatibility with your specific vehicle's year and model.

What makes Laser Iridium spark plugs different?

Laser Iridium spark plugs, like the NGK SILZKFR8D7S, feature an ultra-fine tip made of iridium and a platinum inlay on the ground electrode. This design provides superior ignitability, a slow wear rate, and a long service life compared to standard spark plugs.

How often should I replace these spark plugs?

As these are high-performance, long-life iridium spark plugs, they are designed for extended service intervals. Consult your vehicle's owner's manual or a qualified mechanic for the recommended replacement schedule for your specific car model.

Can I adjust the gap on this spark plug?

Laser Iridium spark plugs are typically engineered with a precise factory pre-set gap and are not meant to be adjusted. Adjusting the gap can damage the fine iridium tip. Always use them as they come from the manufacturer or verify the gap with a proper gauge if specified by the vehicle manufacturer for replacement.

What are the dimensions of this spark plug?

The NGK SILZKFR8D7S / 95875 has a spanner size of 14mm, an outer thread of 12.0mm, a thread length of 26.5mm, and a spark position of 5.0mm.

What is the benefit of trivalent metal plating?

The trivalent metal plating provides superior resistance to corrosion and anti-seizing properties, which helps ensure easier removal during future maintenance and protects the threads.

Troubleshooting

Engine misfires or rough idle

Ensure the spark plug is correctly gapped (if applicable, though laser iridium often comes pre-gapped) and properly torqued. Check for any signs of damage to the plug or ignition system components.

Reduced fuel economy

Verify the spark plug is the correct type for your vehicle and has been installed correctly. Consult your vehicle's maintenance schedule for recommended spark plug replacement intervals.

Difficulty starting the engine

Check the connections to the ignition coil and ensure the spark plug is securely seated. A faulty spark plug can impact starting ability.

Setup, Compatibility & Care

Compatibility Verification: Before installation, always confirm that this spark plug is listed as a direct replacement for your vehicle's original equipment. This NGK part (95875) replaces Mercedes part numbers including 0041596503, 0041596803, 0041597203, 0041597503, A0041596503, A0041596803, A0041597203, and A0041597503, and is suitable for models such as Mercedes A Class, B Class, C Class, E Class, GLA Class, and S Class.

Installation: Installation should be performed by a qualified mechanic or individual with experience in automotive repair. Use a torque wrench to tighten the spark plug to the manufacturer's specified torque. Ensure the spark plug is correctly seated to prevent cross-threading or damage to the cylinder head. The correct spanner size is 14mm, with an outer thread of 12.0mm and a thread length of 26.5mm.

Care: Spark plugs are not typically user-serviceable components. They are designed for long-term use and replacement at recommended service intervals. Avoid using any cleaning agents or abrasive materials on the spark plug itself. If the spark plug appears damaged or fouled during inspection, it should be replaced.
