NGK FR5EI Spark Plug (Stock No. 1313)
The NGK FR5EI is a reliable, standard spark plug designed for clean ignition and stable performance. It uses a copper core for better heat control and a nickel alloy tip for durability. The built-in resistor helps reduce electrical noise that can affect the radio or ECU.
This plug suits everyday driving and light performance use. Expect smooth idle, consistent starts, and dependable spark under load. It is a sensible refresh for ageing ignition systems, and a good baseline before tuning.
Use the site’s vehicle lookup to confirm fitment, or check the Vehicle Fitment tab for full details.
Why it matters
- Strong, consistent spark for smoother running and better throttle response
- Good heat control to resist fouling in stop-start use
- Resistor design reduces electrical interference with sensitive electronics

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.
