NGK DCPR9EIX Iridium IX Spark Plug – Stock No. 2316
The NGK DCPR9EIX is a high-performance iridium spark plug designed for strong ignition, stable combustion, and long service life. It uses a fine-wire iridium centre electrode to fire easily under load and at high RPM. This helps cold starts, throttle response, and consistency, especially in tuned or hard-driven engines.
The NGK heat range 9 is a colder plug. This helps control combustion temperatures in performance use. It also resists fouling during repeated short trips.
Use this plug where DCPR9E-type plugs are specified. It is commonly used in high-performance motorcycle and powersports engines. Always confirm fitment with the vehicle lookup or the Vehicle Fitment tab.
Why choose this plug
- Fine-wire iridium tip for a strong, stable spark
- Improved ignition under high load and high RPM
- Colder heat range for performance and track use where specified
- Resistor design to reduce electrical interference with ECUs and sensors

Type approval ensures that an aftermarket component will reach, or exceed the performance standard of the corresponding OE part.
Type-approval then, is a certain guarantee that an end user will receive a product of OE equivalent performance attributes.
Products on the Progressive Parts website that meet this approval will be clearly marked or labelled EC or ECE approved.
