NGK ILKR9Q7G Laser Iridium Spark Plug (Stock No. 97312)
This NGK Laser Iridium spark plug is built for stable ignition under high load and high boost. The fine iridium centre electrode needs less voltage to fire, which helps cold starts and smooth idle. A platinum pad on the ground electrode reduces wear, so the gap stays consistent for longer.
The NGK heat range 9 is a colder plug. This helps control combustion temperatures on tuned or hard-driven engines, reducing the risk of knock and misfire. It is also a resistor type to cut electrical noise that can affect the ECU.
If you are upgrading power or running sustained high temperatures, this is a reliable choice. Always follow your vehicle’s OE gap and service interval.
Use the site’s vehicle lookup to confirm fitment, or check the Vehicle Fitment tab for full details.

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.
