A Terrific Spark Plug For My Motorcycle By edev5 on Dec 03, 2009 - Updated Oct 15, 2011

My hubby bought this spark plug for my motorcycle, Honda Astrea Star. My motorcycle often has to be replaced its spark plug every now and then because I don't know, maybe because it's an old motorcycle (it was produced in 1994, so it's been 15 years in my possession!). The spark plug that my hubby bought for my motorcycle is usually this one by NGK, model C7HSA. The sparkplug as it measures on the packaging is 10mm diameter and 12.7mm or (1/2in). As a warning, this thing can be used in any vehicles except in airplanes and motored para sailing, because those air vehicles would need special spark plug designed only for them. It's perfectly depicted on the warning picture on the packaging. It doesn't come with instruction leaflet or manual book, but there are pictures printed on the packaging depicting the step-by-step instruction on how to install this on the storage battery. With this instruction, the installation is made easy and my hubby doesn't have difficulty at all when installing it. Overall, we're satisfied with the work of this spark plug because it always goes smoothly on my motorcyle.
