NGK ILFR7H Laser Iridium Spark Plug – Stock No. 5245
The NGK ILFR7H is a long-life Laser Iridium spark plug designed for clean ignition, stable idle, and reliable performance under load. It uses a fine iridium centre electrode and a platinum-tipped ground electrode. This keeps the spark strong while reducing wear, so performance stays consistent over time.
Iridium needs less voltage to spark. That helps cold starts and smooth running, especially on turbo and high-compression engines. The resistor design also helps cut electrical noise that can affect the ECU.
Use this plug as a high-quality replacement or light performance upgrade. It is pre-gapped and ready to install. Always confirm fitment using our vehicle lookup or check the Vehicle Fitment tab.

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.
