Upgrade your ignition system with the A-Premium kit that combines four high-energy ignition coils with four iridium spark plugs. Designed for broad Mazda compatibility, this set aims to deliver a more consistent spark, smoother idle, and reliable starts across daily driving and longer trips.

Iridium center electrodes are known for durability and a stable spark. The design can contribute to a steadier idle, potential fuel-efficiency benefits, and lower emissions under typical driving conditions. These are possible outcomes rather than guarantees.
