NGK IFR5N10 Iridium Spark Plug – Stock No. 7866
This NGK IFR5N10 is a premium iridium spark plug designed for clean, reliable ignition. It helps the engine start easily, idle smoothly, and respond better under load. The fine iridium centre electrode needs less voltage to spark, which can improve combustion stability and reduce misfires. It is built for long service life and consistent performance.
Use this plug where IFR5N10 is specified by the vehicle maker. If you are upgrading, match the heat range and reach to your engine. Check fitment using the site’s vehicle lookup or the Vehicle Fitment tab.
- Fine iridium centre electrode for a strong, stable spark
- Resistor design to reduce electrical noise that can affect sensors and the radio
- Factory-set gap for easy installation – verify against your vehicle spec
Installation notes
Fit only to cold engines. Check and set the gap to your vehicle spec if required, using light pressure to avoid damaging the fine tip. Apply a small amount of anti-seize only if recommended by the vehicle maker. Tighten to the correct torque. Re-check coil boots and leads for wear. Do not file or sand the iridium tip.

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.
