About this part

Product Details

NGK is well-known for making reliable ignition components, and their Laser Iridium spark plugs are a prime example of that. These are built specifically for vehicles that came with OE iridium alloy plugs, like your Audi S8. They combine high ignitability with excellent longevity, making them a solid choice for keeping your engine running smoothly.

The center electrode on these plugs uses iridium, which is about six times harder than platinum. This means they're built to last a long time. Plus, the pure alumina ceramic insulator and a 98 percent pure copper core help prevent the plug from getting too hot, ensuring dependable starts every time. You'll also find a platinum fine wire tip on the ground electrode. This design helps with even wear, especially in modern distributorless ignition systems, and contributes to improved spark performance.
