NGK ZFR5E-11 Spark Plug – Stock No. 4435
The NGK ZFR5E-11 is a reliable, road-focused spark plug designed for clean, consistent ignition. It uses a copper core for strong heat control and a nickel alloy tip for long service life. The built-in resistor reduces electrical noise that can affect the radio or ECU. The projected tip helps start the burn in the right place for smooth running.
It is a solid choice for standard and mildly tuned petrol engines that specify an NGK heat range 5 plug. Expect easy cold starts, stable idle, and dependable performance over a typical service interval.
Always set the gap to your vehicle’s specification. Pre-set is 1.1 mm, but engines can vary.
Use the vehicle lookup to confirm fitment, or check the Vehicle Fitment tab for full details.

In the words of the Vehicle Standards Agency (VCA), type approval provides "confirmation that production and samples of a design will meet specified performance standards".
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.
