Improve fuel economy, lower emissions, and start your car more quickly with NGK TR-5 or TR-6 spark plugs. Featuring a 0.04-inch gap, which may improve engine idling, these plugs feature a 0.6-millimeter laser-welded platinum tip that reduces required voltage while proving extremely resistant to high heat. And thanks to the trivalent metal plating, it’s also resistant to corrosion and seizing. High compression or boosted motors may see reduced detonation and increased performance by running the colder TR-6 plug.
Note: This drop includes eight spark plugs. At checkout, you can choose between the TR-5 (+$1), TR-6, or TR6IX (+$35). Each option is limited to 25 sets of 8 spark plugs.
