NGK SIFR6A11 Laser Iridium Spark Plug – Stock 127
The NGK SIFR6A11 is a premium Laser Iridium spark plug designed for clean, reliable ignition. It delivers a strong spark for smoother idle, sharp throttle response and stable performance. The iridium centre tip and platinum pad ground electrode resist wear, so the gap stays consistent for many miles.
Use this plug as a high quality replacement on standard or lightly tuned engines that require an NGK heat range 6 plug and 1.1 mm gap. Always confirm fitment with the vehicle lookup or check the Vehicle Fitment tab.
- Fine-wire iridium tip for strong ignition and efficient combustion
- Platinum pad ground for long service life and stable gap
- Built-in resistor for reduced electrical noise
- Factory-set 1.1 mm gap for quick installation
Installation note: Handle the fine iridium tip with care. Do not force the gap. Use a torque wrench and follow manufacturer torque guidance.

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.
