NGK LKR8A Spark Plug – Stock No. 5214
The NGK LKR8A is a high-quality spark plug designed for reliable ignition under load. It uses a resistor design to reduce electrical noise and protect sensitive electronics like the ECU. The heat range 8 rating suits engines that run hotter, such as turbocharged petrol engines or performance setups.
A fresh plug helps the engine start cleanly, idle smoothly, and pull harder through the revs. It can also improve fuel economy and reduce misfires when replacing worn plugs. If you tune or drive hard, a correctly rated plug like this helps control combustion and resists overheating.
Fitment notes:
– Suits many modern petrol engines that specify an NGK heat range 8, resistor plug.
– Often chosen for turbo engines needing a colder plug for knock control.
– Use our 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.
