NGK PFR5N-11 Platinum Spark Plug – Stock No. 5838
This NGK platinum spark plug delivers a clean, consistent spark for everyday driving and light performance use. The fine-wire platinum centre reduces voltage demand, helping cold starts and smooth idle. It is built for long service life compared with standard copper plugs, while keeping emissions and fuel economy stable when the engine is under load.
It is a resistor type to cut radio interference and protect sensitive electronics. The 1.1 mm factory-set gap makes installation straightforward. Use a torque wrench for best results.

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.
