DENSO IRIDIUM TOUGH PLUGS

Iridium Tough plugs use the same .4mm center electrode technology but also benefit from a platinum contact on the earth electrode. This gives all the performance benefits seen in the Iridium Power plugs, together with an extremely long life. These plugs are particularly beneficial in high powered turbo application where plug life has historically been problematic. They can be used in all applications where plug lifetime is as important as maximising performance.
