NGK PZFR5N-11T Spark Plug (Stock 7742)
This NGK spark plug is built for reliable ignition, smooth running, and long service life. It uses a fine platinum centre electrode to maintain a strong spark with less voltage, helping cold starts and throttle response. The projected tip places the spark where the burn is most efficient, while the resistor design helps reduce radio interference and ECU noise.
It is pre-gapped to 1.1 mm and designed to last longer than standard copper plugs, with consistent performance over time. This makes it a good upgrade for daily use, light tuning, and regular service intervals.
- Stable spark for cleaner combustion and smoother idle
- Platinum centre electrode for long life and consistent performance
- Projected tip aids efficient flame spread and response
Always confirm fitment with the Vehicle Fitment tab or the site’s vehicle lookup before ordering.

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.
