NGK CR9EHIX-9 Iridium IX Spark Plug (Stock No. 6216)
The NGK CR9EHIX-9 is a high-quality iridium spark plug designed for reliable ignition, strong spark, and long life. It uses a fine iridium centre electrode to reduce the voltage needed to fire, which helps cold starts and throttle response. It also resists fouling and wear better than standard copper plugs.
This plug is commonly used in many performance-focused motorcycles that use 10 mm, long-reach spark plugs. Always confirm with the vehicle lookup or the Vehicle Fitment tab before purchase.
- Iridium centre electrode for a stable spark and long service life
- Resistor design to reduce electrical noise and protect ECU and sensors
- Pre-set 0.9 mm gap for quick installation

What it does and why it matters
A strong, consistent spark helps the engine burn fuel cleanly. That means smoother idle, better response, and steady performance. The fine iridium tip needs less voltage to fire, which helps under load and at high revs. It also lasts longer than standard plugs, so service intervals can be extended in many cases.
Note: Always check your owner’s manual for the correct heat range, reach, and gap. Use our vehicle lookup or the Vehicle Fitment tab to confirm this exact part for your engine.
The price displayed is for a single plug, please add the desired amount to your basket.

In the words of the Vehicle Standards Agency (VCA), type approval provides "confirmation that production and samples of a design will meet specified performance standards".
For emissions components this encompasses noise, emissions and balanced back pressure, which have a strong influence on maintaining engine performance (power), and fuel efficiency. 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.
