Laser Iridium Spark Plug for RMZ450

NGK 92743 is a Laser Iridium High Ignitability spark plug built for direct OE-style service on the Suzuki RMZ450. It combines an iridium center electrode with a dual fine ground electrode design to support consistent ignition performance and stable combustion.

Key Features

  • Laser Iridium High Ignitability design for precise spark delivery.
  • Iridium center electrode tip with a copper core for efficient conductivity.
  • Dual fine ground electrode layout with a standard ground configuration.
  • Pre-gapped to 0.040 inch for the listed application.
  • Flat seat, 10 mm thread diameter, and 5/8 hex size.
  • NGK part number 92743, also identified as DIMR8C10.

Detailed Description

NGK 92743 is engineered as an OE-spec spark plug for Suzuki RMZ450 applications from 2005-2024. The Laser Iridium construction uses a fine iridium tip and a nickel ground electrode to promote reliable ignition under demanding operating conditions, while the 5000 ohm resistor helps control electrical noise. The flat seat and 0.75 inch reach match the listed fitment requirements, making this NGK spark plug a direct service part for RMZ450 maintenance. The part number 92743 appears on the box as stock number 92743 and cross-references Edelmann 92743 for the same application.

What It Helps Address

  • Hard starting caused by worn or fouled spark plugs.
  • Misfire concerns from weak or inconsistent spark output.
  • Rough idle and throttle hesitation under load.
  • Reduced ignition efficiency from incorrect gap or heat range.
  • Electrical interference related to plug resistance.

Installation Notes and Tips

Verify the specified 0.040 inch gap before installation and confirm the flat seat, 10 mm thread diameter, and 0.75 inch reach match the cylinder head requirements. Use the listed fitment details for Suzuki RMZ450 models only, and follow the service manual torque specification during installation. NGK 92743 is listed for 2005-2024 Suzuki RMZ450 applications.
