A-Premium Iridium & Platinum Spark Plugs – 6-Pack for Ford, Chevrolet, Mercedes & More

Discover the A-Premium Iridium & Platinum Spark Plugs, a 6-pack built to support a wide range of engines with reliable ignition and lasting performance. These plugs blend an iridium tip with a platinum core to promote consistent spark delivery across daily driving and longer trips, without requiring dramatic changes to your routine maintenance.

What makes these plugs stand out is the attention to precise engineering: a focused gap of 0.035-0.039 inches helps optimize combustion and throttle response under varied conditions. The hex size of 5/8 inch is compatible with common tools, while the 14 mm thread diameter and 17.98 mm reach are designed to fit a broad lineup of 4- and 6-cylinder engines. An insulator height of 53 mm supports stable performance in engines that demand robust heat management, helping reduce misfires during aggressive acceleration or extended highway runs.

Engineered for longevity, these plugs are recommended for replacement at mileage intervals around 80,000 to 100,000 miles, depending on vehicle and driving conditions. The six-pack format is convenient for owners who service multiple vehicles or want reliable spares on hand for regular maintenance cycles.
