Motorcycle Ignition will not be complete without something to jump an arc to inside the combustion chamber to Ignite the compressed mixture may it be Carbureted or Fuel Injected system of Front end Ignition. More users often tend to change Ignition boxes, remapped the ECU, change ignition coils, Lightened something to have at least a very reliable and at least above optimum Ignition system. The least Item on their list of changing was the dreaded SPARK PLUG!!!!
There are many to choose from. starting to ORDINARY all the way up to more expensive ones like Iridium and or Platinum, but how do they really produces the ARC or spark when they are bolted on the plug hole. Do you really see how they spark and compare them to others? Is there a way to see them arc and be visible to our eye.
Well I did an experiment on some of what I have on my workshop, in which I used them before on my 16 year old small engine motorcycle. As always I set up up my DC-CDI testing equipment to perform this experiment.
Spark Plug to be tested today are as follows
- AT7C platinum--normally sold by Chinese online shopping site, They are many rebranded of this but all of them came from AT7C base item
- Ordinary AT7C--the non platinum type mainly in white color for distinguisment.
- Denso Iridium IUF22--very known worldwide and it is not cheap. I bought i before around year 2008 for around 15$
- Bosch Platinum UR4A--The composition of the center core of this plug is somehow hidden and just a portion of it is exposed on the ceramic coating.
- AT7C 3 Electrode--The Chinese 3 electrode type with the center element is like a side gaped type.
The test will be very simple. The DC-CDI will fire the coil at 1000RPM and 10,000RPM to just see the intensity of the 5 spark plug..The color is not much seen by the camera used but in my own eyes they all differ. Other plug was white all through out, One plug was orange arc, There is a plug that arcs like a NEW YEAR luces.

The AT7C can replace the following brand and model.

Will changing from standard ordinary plug to platinum increases my engine power?
ReplyDeleteHi! Cassbee, one thing is for sure. If u see an orange color of spark on your spark plug try changing to other type like platinum and or iridium, for a weak spark will rob power on your engine. A good spark will provide better fuel economy and power.
