Description:
Platinum is one of the rarest metals on earth and one of the most valuable. However, it also happens to be an excellent material for spark plugs, thanks to its superior resistance to corrosion and erosion in harsh environments – like those inside modern, high-tech engines. DENSO Double Platinum spark plugs incorporate the precious metal on both the center and ground electrodes, not just on the center electrode as with conventional platinum plugs. The result is a significant improvement in spark plug life. DENSO engineering studies show that Double Platinum plugs can run longer with reduced erosion, minimizing spark gap growth throughout the life of the plug. The bottom line: your car can run better, longer.
Platinum center electrode
Platinum ground electrode
Premium shell construction with machine-rolled threads
Benefits
Sustained spark performance over 60,000 miles
Reduced secondary required voltage, increased ignition efficiency
Satisfied customers, reduced shop comebacks

Q: Do spark plugs come in sets of 4?
A: Spark plugs are sold individually (unless otherwise noted) and should be replaced all at the same time.
Q: How do you install spark plugs?
A: Spark plugs are installed by using a spark plug socket. Simply remove the spark plug wires and unbolt the plugs. Replace and gap the new plugs and you should be set.
Q: What are spark plugs? Why buy spark plugs?
A: Spark plugs create a spark in the combustion chamber of the engine, igniting the fuel and air mixture and getting the engine running. When you're running a higher horsepower motor, spark plugs play a big role. A colder heat range plug (which is what more aftermarket spark plugs are) has less insulation; it cools off faster between firing and the introduction of a fresh charge of the air/fuel mixture. A hot plug can ignite the air/fuel mixture before the plug actually fires. This is called pre-ignition, a form of detonation, and can destroy a motor. When upgrading the power of your vehicle, make sure to look into a colder range spark plug.
