What makes these NGK spark plugs different from standard ones?

These NGK Ruthenium HX plugs use a special Ruthenium alloy for the center electrode, which is more durable and helps create a stronger spark. They also have a fine wire design on both the center and ground electrodes to promote better ignitability and a more complete fuel burn.

Do these spark plugs come with anti-seize on the threads?

The spark plugs feature trivalent metal plating, which offers superior anti-corrosion and anti-seizing properties. It's always a good idea to check the manufacturer's installation instructions for any specific recommendations regarding anti-seize compound.

What is the benefit of the corrugated ribs on the ceramic insulator?

The corrugated ribs on the ceramic insulator help prevent flashover, which is an electrical discharge that can occur along the surface of the insulator. This helps ensure the spark reliably jumps across the electrode gap.

Product Details

You get a box of four NGK Ruthenium HX spark plugs, part number LKR7BHX. These are designed for modern engines that need a strong spark to run efficiently. They feature a unique Ruthenium alloy center electrode and a platinum fine wire ground electrode, which helps concentrate the spark for a more complete fuel burn. This can lead to a quicker throttle response, a smoother idle, and easier cold starts.

The design of these plugs, with their fine wire electrodes and pure alumina silicate ceramic insulator, helps transfer heat away from the plug tip. This helps keep the plug operating at the right temperature. The trivalent metal plating on the outside helps prevent corrosion and makes them easier to remove later on. These are a solid option if you're looking for an updated spark plug with the latest technology for your vehicle.

These spark plugs fit a wide range of vehicles, including many Chrysler, Dodge, and Mercedes-Benz models. Always check the fitment guide to make sure they're the right ones for your specific car.
