What makes the trivalent metal plating beneficial?

The trivalent metal plating on these NGK spark plugs provides excellent resistance to corrosion and seizing. This makes it significantly easier to install the new plugs and remove them later if needed, without damaging the cylinder head.

What is the purpose of the copper core in these spark plugs?

The 98% pure copper core is a key component for heat management. Copper is a highly conductive material, allowing it to efficiently dissipate heat away from the spark plug's firing tip and into the cylinder head, which helps maintain optimal operating temperatures.

Are these spark plugs sold individually or as a set?

These NGK Standard spark plugs are sold in a box of four, which is the correct quantity for most 4-cylinder engines like the one in your Saturn SL2.

Product Details

NGK is well-known for making reliable ignition components that are often the original equipment on many vehicles. These NGK Standard spark plugs are a prime example, offering the same dependable performance you'd expect from the factory. They are designed to fit your 1991-2002 Saturn SL2, ensuring your engine runs smoothly.

Inside each plug, a pure alumina silicate ceramic insulator provides excellent strength and helps transfer heat away from the firing tip, which is crucial for consistent performance. The core is made of 98% pure copper, known for its great conductivity and ability to handle a wide range of operating temperatures. NGK also uses a trivalent metal plating on the shell, which is a smart touch that makes installation and removal much easier by resisting corrosion and seizing.

You'll also find corrugated ribs on the insulator to help prevent flashover, and triple seals are used to keep combustion gases from leaking out. These plugs are built for a long life and to keep your engine performing at its best.
