It is general question concerning DENSO SPARK PLUG that is often.
 |
I'm using Iridium Power. If there is carbon fouling, can I use a brass brush to clean the plugs? |
|
| Because Iridium Power's center electrode has a fine 0.4mm diameter, there is a chance that this electrode could be bent by a brass brush. If you having the plug cleaned, a sandblaster-type plug cleaner found in maintenance shops is preferable. If this is the case, keep the air pressure low and clean the plug for as short a time period as possible. Also, one trick would be to dissolve the carbon with an engine conditioner or a similar chemical agent. (Parts cleaners will not dissolve carbon). After applying it, take a nylon brush (don't use a wire brush) and scrub it off, wash it well, and dry it off. Repeat this procedure three or four times to remove any carbon. DENSO has confirmed that this does not return the performance of the plugs to 100%, so please use this as a stopgap measure. |
