Though these vehicles frequently use a low heat range, the heat ranges available for Iridium Power starts with IW16, so choose one that matches the type of driving you do. Better accelerator response and torque can be expected with Iridium Power, which has excellent ignitability. Recently, the space to install plugs in trial vehicles has shrunk, and there is a demand for miniature plugs. In these cases try the IK types. However, the space between the plug cord and the insulator will require waterproofing. |
