NGK Ruthenium HX Spark Plug Box of 4 (LKR8BHX-S)

If you're looking to get the most out of your 2007-2012 Acura RDX's engine, especially if it's a newer model that demands high ignitability, these NGK Ruthenium HX spark plugs are a solid option. They use a special Ruthenium alloy in the center electrode, which is known for being very durable and helping to create a strong spark. This advanced tip technology is designed to ignite the air-fuel mixture more completely.

What that means for you is a more efficient burn, which can lead to a quicker throttle response when you step on the gas, a smoother idle when the car is stopped, and better performance when starting up in cold weather. The plugs also feature a fine wire ground electrode made of platinum, and the ceramic insulator is strong and helps manage heat effectively. Plus, the metal plating on the outside helps prevent corrosion and makes them easier to remove later on.

This set comes with four plugs, which is exactly what you need for your RDX. They are built with a copper core to help dissipate heat and corrugated ribs on the insulator to prevent spark flashover, ensuring the spark goes where it's supposed to.
