NGK IFR5G-11K Laser Iridium Spark Plug – NGK 3107
The NGK IFR5G-11K is a premium Laser Iridium spark plug designed for long life and consistent ignition. It delivers a clean, stable spark, helping cold starts, smooth idle and reliable performance under load. It is built to OE standards and is ideal as a high-quality replacement for many modern petrol engines that specify this plug type.
Expect improved throttle response and efficient combustion over worn plugs. It will not add big power on its own, but it supports consistent performance and can help maintain fuel economy when replacing tired plugs.
Use our vehicle lookup to confirm fitment, or check the Vehicle Fitment tab for full details. This plug suits engines that require a 14 mm thread, 19 mm reach, resistor type, and a 1.1 mm preset gap.
- Laser-welded iridium centre tip for strong spark and long life
- Platinum pad on ground electrode to reduce wear
- Resistor design to minimise radio interference and ECU noise

Installation notes
– Check and adjust gap only if the vehicle maker specifies a different gap. Use a proper wire gauge tool and avoid prying on the fine tip.
– Tighten to the vehicle maker’s torque spec. As a guide for 14 mm gasket plugs in aluminium heads, 18-25 Nm is typical.
Always install into a cool engine and start threading by hand to avoid cross-threading.

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.
