A spark plug is a device for delivering electric current from an ignition system to the combustion chamber of a spark-ignition engine to ignite the compressed fuel/air mixture by an electric spark, while containing combustion pressure within the engine. Didn’t realize that little thing did so much huh? Well in the world of spark plugs there is a lot that can be adjusted or changed to achieve more power, better fuel efficiency, and overall improvement in the combustion process. K and G Cycles (www.kandgcycles.com) understands this and that is why we offer you a wide range of spark plugs for your motorcycle.
As technology has advanced through the ages, we have been given more spark plug choices than ever before. We now have the choice of upgrading spark plugs based on the core element or different electrode designs. Now, as sure as the day is long, there will be those that swear by “Brand X” and according to them there is no other. I believe brand choice is a personal preference, however core and electrode differences can mean increased power, fuel economy, or a more efficient fuel burn.
Copper Spark Plugs
Copper spark plugs are generally considered to have the best performance of any spark plug type. This is potentially different from what advertising companies suggest, but the other metals are, unfortunately, not as conductive in general as copper is. Platinum and iridium plugs are more likely to overheat, which causes damage to the plug components and can compromise the delivery of the spark to the engine block.
Platinum and Iridium Plugs
Platinum and Iridium plugs perform at a lower level than copper spark plugs, because they are less conductive and they tend to overheat. However, the overall longevity of these two types of metal is better than copper plugs. In reality, copper has the best performance of all three and the worst longevity. Platinum has good longevity and the worst performance. Iridium has good longevity and a performance that is decent, which is why iridium plugs tend to be more expensive than any other type. Still, the difference between these plugs in terms of overall quality is minimal, as there is a trade off for each.
Most copper plugs need to be changed every 10,000 miles or so. Platinum and Iridium plugs can often go for twice that before they require changing, but the overall performance will not be as good and you may have to deal with overheating of the plugs. This is potentially not worth the added cost of both platinum and iridium spark plugs, although the decision will depend upon your preference.
Every once in awhile it is a good idea to check your spark plugs to see the condition of the plugs and analyze the burn pattern to make sure your motor is healthy. Our riding habits contribute to overall spark plug condition and performance, so it is important to keep an eye on them.
When choosing the spark plugs you are going to use as replacements, it is a great idea to educate yourself and understand the options you have. If you need any help call the Pros at K and G Cycles (www.kandgcycles.com) and they can help you select the right spark plug for you and your riding style.
