NGK Spark Plugs Pack of 4 — 3108 Standard OEM-Quality Replacement for Petrol Engines, Factory Gap

NGK 3108 is a genuine four-pack of NGK Standard spark plugs designed as a direct replacement for compatible gasoline engines.

This listing describes the NGK 3108 Pack of 4 Spark Plugs — standard, OEM-quality ignition parts sold in original NGK packaging. These plugs are intended to replace worn or damaged spark plugs with a factory-equivalent unit, supplied as a four-count set that includes the original packaging and hardware for straightforward installation. Always verify fitment for your specific vehicle before purchase.

What does the NGK 3108 replace in my ignition system?

The NGK 3108 replaces worn or failed spark plugs that no longer provide reliable spark or consistent combustion. It installs where the original spark plugs were removed and restores the expected gap and electrode configuration for compatible engines.

• Sold as a pack of four to service multiple cylinders or keep a spare set.
• Factory-standard electrode geometry for consistent firing.
• Includes original NGK packaging and hardware for installation.

How do I confirm these plugs fit my vehicle?

Fitment should be confirmed using your vehicle’s make, model, year and engine code, or through the seller’s vehicle compatibility tool. NGK part numbers correspond to specific gap, thread length, and reach — matching those specs to your vehicle avoids installation issues.

• Check vehicle fitment tools (e.g., Amazon Confirmed Fit) before ordering.
• Compare NGK 3108 thread size, reach, and resistor type to OEM spec.
• Reference your vehicle manual or a professional mechanic if unsure.

Why choose genuine NGK Standard spark plugs instead of aftermarket options?

Genuine NGK plugs are manufactured to the company’s original specifications, offering consistent manufacturing tolerances and standardized performance characteristics. Choosing OEM-equivalent parts reduces the risk of mismatch and helps maintain the intended ignition characteristics of your engine.

• NGK quality control and material standards for consistent fit and function.
• Direct replacement design minimizes installation differences from OEM parts.
• Pack of four provides cost-effective servicing for multiple cylinders.

What should I expect during installation and maintenance?

Installation follows standard spark plug replacement procedures: remove the old plugs, verify the new plug gap if required, thread the NGK 3108 by hand to avoid cross-threading, and torque to the vehicle manufacturer’s specification. Routine inspection and replacement intervals depend on driving conditions and vehicle recommendations.

• Verify or set plug gap per your vehicle’s specification before installation.
• Use a torque wrench and the correct torque value to avoid damage.
• Inspect ignition boots and wires or coils while replacing plugs.

Who is this for: The NGK 3108 Pack of 4 Spark Plugs is suited for drivers, independent mechanics, and fleet technicians seeking a genuine NGK standard replacement in a four-pack. It’s ideal when you need factory-equivalent parts for maintenance or to replace worn plugs on compatible gasoline engines, and for anyone who prefers original-brand components and sealed NGK packaging for reliability and fitment assurance.
