Cold Spark Plug APR Iridium Pro

Product information

APR Pro spark plugs are made of iridium and are specially developed for tuned vehicles. Iridium is considered one of the toughest materials that can be used to make spark plugs. In addition, the material brings very useful properties such as a cooler operating temperature, prevention of pre-ignition, longer durability with a higher melting point and a strong spark with less voltage. What's more, the electrode is harder and more resistant than other materials and can dissipate heat better. This creates better protection against cracking and melting compared with standard plugs. APR Pro spark plugs are ideal for vehicles with high power output. The spark plugs can also be combined with our ignition coils. They are equivalent to Bosch 3, Denso IKH27 or NGK 9.
