My Buying Guide on Honda 400Ex Spark Plug

As an avid ATV rider, I have had my fair share of experience with different spark plugs for my Honda 400Ex. After trying out various options, I have found the perfect spark plug for my vehicle and decided to share my knowledge with fellow riders who might be looking to purchase a new spark plug. In this guide, I will be discussing the important factors to consider when buying a spark plug for your Honda 400Ex.

Compatibility

The first and most important factor to consider when buying a spark plug for your Honda 400Ex is its compatibility with your vehicle. It is crucial to check the manufacturer’s specifications and make sure that the spark plug you are purchasing is compatible with your ATV model. Installing an incompatible spark plug can lead to engine damage and affect the performance of your vehicle.

Material

The material of the spark plug plays a vital role in its durability and performance. Most Honda 400Ex owners prefer using iridium or platinum spark plugs as they have a longer lifespan compared to traditional copper ones. These materials also provide better conductivity and produce a stronger spark, resulting in improved engine performance.

Heat Range

The heat range of a spark plug refers to its ability to dissipate heat from the combustion chamber. It is essential to choose a spark plug with an appropriate heat range for your riding style and environment. For instance, if you ride in hot weather conditions or engage in aggressive riding, you will need a spark plug with a colder heat range to prevent overheating.

Resistor or Non-Resistor

Spark plugs come in two types – resistor and non-resistor. A resistor type has an added resistance that reduces electromagnetic interference, while non-resistor types do not have this feature. For Honda 400Ex, it is recommended to choose a non-resistor type as it provides better throttle response and improved ignition timing.

Brand

When it comes to choosing the brand of your Honda 400Ex spark plug, it is always best to stick with reputable brands known for their quality products. Some popular brands among ATV riders include NGK, Denso, and Bosch. These brands have been tried and tested by many riders and have proven to be reliable.

Price

While purchasing a cheaper option may seem like a cost-effective choice initially, it can end up costing you more in the long run if the quality is compromised. On the other hand, expensive does not always mean better either. It is essential to find a balance between quality and price when buying a Honda 400Ex spark plug.

Maintenance Tips

Once you have purchased your new Honda 400Ex spark plug, it is crucial to maintain it properly for optimal performance. Regularly inspecting and cleaning the spark plug can help extend its lifespan and prevent any potential issues.

In conclusion, choosing the right spark plug for your Honda 400Ex can significantly impact its performance on the road or trails. By considering factors such as compatibility, material, heat range, resistor/non-resistor type, brand reputation, price point, and maintenance tips; you can make an informed decision when purchasing a new spark plug for your beloved ATV.
