Spark Plug Buyer's Guide for Harley Davidson Motorcycles

Compatibility

You first need to make sure that your desired spark plug is compatible with the make & model and the age of your vehicle. For example, a spark plug designed for a 60 cc knucklehead engine will not work with a shovelhead 82cc engine and vice versa. Using the wrong spark plug can cause a whole host of engine issues.

Spark plug coating

The coating of a spark plug provides necessary electrical resistance. There are 3 main types of spark plug coating:

在大多数情况下，您想为哈雷·戴维森（Harley Davidson）留下虹膜火花塞。虹膜是一种强大的材料，可以承受很多电阻。但是，某些铂火花塞可以很好地服务。但是，您将需要避免使用铜火花塞，因为它们不如鸢尾或铂金高质量。

Build quality & functionality

The best spark plugs are made from durable precious metals such as platinum and iridium. These metals have very high melting points and can handle a lot of electrical resistance before failing. Additional, good quality spark plugs generally have ceramic insulators.

Heat range & insulation

Spark plugs are rated for a particular temperature operation. Most spark plugs only work when their internal electrode temperature is between 500-950 degrees-C. Thus spark plugs also require good insulation to keep the heat from leaking. In general, high-quality spark plugs have ceramic insulation. Ceramic has high heat retention and is extremely durable.

Thread size & gap style

线程确定火花塞螺钉如何进入端口，而间隙是指发生电气放电的空间。除非制造商指定，否则火花塞间隙绝不应超过0.055“。当前有三种螺纹尺寸用于摩托车火花塞：

Lifespan & mileage

大多数摩托车火花塞都设计为持久 at least 15,000 miles, or about once every 1-2 years or so, depending on how often you ride it. The more you ride your motorcycle, the more frequently you will have to replace your spark plugs. You should never ride more than 30,000 miles without changing your spark plugs.

价格和保修

Most motorcycle spark plugs will cost between $20 on the low end to $90-$150 on the high end. Most of the time, copper spark plugs are the cheapest, while iridium and platinum spark plugs are more expensive. You should also look for spark plugs that have a warranty agreement so you can get a replacement in case they fail.
