The APR Iridium Pro Spark Plugs are an excellent upgrade for tuned engines.
Made from Iridium, which is one of the strongest materials used in this type of application, they run cooler, resist preignition, last longer than other materials with higher melting points, and require less voltage to produce a strong spark.
The electrode is harder and stronger than other materials and, with its copper core, can dissipate heat more easily, being better protected from melting, cracking, and other limitations found with standard plugs.
Designed for use on tuned and higher output vehicles, they benefit from a plug cooler than the factory heat range.
They are suitable for high boost, high cylinder pressure, high cylinder temperatures, and high power situations, and they pair nicely with a set of APR ignition coils, where applicable.
Always check sizes, gap, and heat range specs before installing.
Installing the wrong length plug can cause damage to the engine, so verification is necessary before installation.
