NGK ILZKR7G7G Laser Iridium Spark Plug
The NGK ILZKR7G7G is a premium Laser Iridium spark plug designed for reliable ignition and long service life. It uses a fine iridium centre electrode for a strong, consistent spark, and a platinum-tipped ground electrode to reduce wear. This helps cold starts, smooth idle, and stable performance under load, especially on tuned or turbocharged petrol engines where a dependable spark matters.
Iridium needs less voltage to fire, so the coil works less hard. That can improve combustion stability and reduce misfires. The plug is resistor type to limit electrical noise that can affect sensors and the ECU. The heat range is 7, offering a good balance for performance-focused road engines while staying safe for daily use.

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.
