NGK PLKR7A Laser Platinum Spark Plug – Stock No. 4288
The NGK PLKR7A is a Laser Platinum spark plug designed for clean, reliable ignition. The fine-wire platinum centre electrode needs less voltage to spark, which helps cold starts, smooth idle, and consistent performance under load. Heat range 7 offers improved resistance to knock in hard use compared to warmer plugs, making it a solid choice for mildly tuned petrol engines that specify this range.
- Stable spark at high RPM and boost
- Long service life from platinum centre electrode
- Good knock resistance with NGK heat range 7
- Smoother idle and better throttle response when replacing worn plugs

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.
