NGK 2668 BKR8EIX Iridium IX Spark Plugs Specification, Features & Applications

The NGK BKR8EIX (2668) is an Iridium IX spark plug designed for high-performance and modified engines. Here’s a detailed overview:

Specifications:

• Part Number: 2668

• Thread Size: M14 x 1.25

• Thread Length: 19.0 mm

• Spanner Size: 16 mm

• Spark Position: 3.0 mm

• Electrode Type: Single Iridium center electrode with tapered cut ground electrode

• Interference Suppression: 5 kΩ

• Seat Type: Gasket seat

• Connector Type: Fixed SAE connector

The fine 0.6 mm Iridium center electrode offers superior durability and a stable spark, while the tapered ground electrode enhances ignitability, acceleration, and fuel efficiency. The trivalent metal plating provides excellent anti-corrosion and anti-seizing properties. These features make the BKR8EIX suitable for high-performance applications and as an upgrade from standard nickel alloy spark plugs.

Features:

1. Iridium Alloy Center Electrode

   • 0.6 mm laser-welded iridium tip for high durability and consistent spark.

   • Melting point over 2,400°C, ideal for high-performance engines.

2. Improved Ignitability

   • Tapered cut ground electrode reduces quenching effect.

   • Delivers quicker throttle response and better cold starts.

3. Anti-Fouling Technology

   • Special insulator nose length prevents carbon build-up.

   • Excellent for engines prone to fouling under heavy loads or idling.

4. Superior Corrosion Resistance

   • Trivalent metal plating for enhanced anti-seizing and corrosion protection.

5. Longer Service Life

   • Outlasts traditional nickel plugs, reducing replacement frequency.

6. Internal Resistor

   • Built-in 5 kΩ resistor suppresses electromagnetic interference (EMI) with electronics.

7. High Combustion Efficiency

   • Promotes a more complete fuel burn for reduced emissions and improved mileage.
