NGK Double Platinum Spark Plug Box of 4 (PRF6A-11)

NGK is well-known for making reliable ignition components, and these Double Platinum spark plugs are a great example of that. If you're working on your 1987-1989 Nissan Pulsar NX, these are designed as an OE equivalent replacement to keep your engine running smoothly.

These plugs use a dual platinum design, with a platinum pad on the ground electrode. This setup helps them wear slowly and evenly, especially in distributorless ignition systems, which contributes to stable idling and a longer service life compared to standard nickel plugs. The pure alumina ceramic insulator helps with heat transfer, and the copper core aids in removing excess heat, preventing the plug from overheating. Plus, the trivalent metal plating on the threads helps resist corrosion and makes them easier to install without seizing.

You'll get a box of four plugs, which is exactly what you need for your Pulsar NX. They're built to provide stable idling, better fuel efficiency, and lower emissions.
