It is general question concerning DENSO SPARK PLUG that is often.
 |
Is there a way to tell them apart when replacing them? |
|
| This can be done by confirming the level of wear (the gap width) on the ground electrode. DENSO's Iridium electrodes are different from conventional products in that their center electrodes hardly wear, and because of this it is better to check for wear on the ground electrode . |
