If you’re a lawn owner, you must know how important it is to have a well-maintained lawn that is lush, green, and healthy. 

To maintain a lawn to that level (that’s lush, green, and healthy), it’s important to keep your lawn mower in excellent working condition, which includes regular maintenance and replacing its parts as needed.

One critical part of a lawn mower’s engine that often gets overlooked is the spark plug. The spark plug plays an important role in igniting the fuel and air mixture in the engine, which is necessary for it to run smoothly. 

But over time, spark plugs wear out and become less effective, resulting in decreased engine performance and causing potential damage such as jacking off while working, not starting when it should, and so on.

However, if you own a Honda lawn mower with a GCV160 engine, you know how frustrating it can be when your mower starts to underperform, jack off, or won’t even start at all because of the spark plug. 

So, you want to change it but don’t know if the one you intend to buy would last longer than expected. And with so many different options on the market, you might get to choose the wrong spark plug for your GCV160 engine that won’t last.

Fortunately, you don’t have to worry as we’ve researched for you. In this blog post, we’ve highlighted the best spark plugs for Honda lawn mower GCV160. We also discuss what factors to consider when selecting a spark plug.

What to Consider When Choosing a Spark Plug for Honda Lawn Mower GCV160

We’ve already listed our top-picked spark plug for the Honda lawn mower. If you’d like a fast review and can’t wait to read till the end, you can go for any on our list.

But if you’d like to read till the end and make a better choice, you first need to understand the factors that make these spark plugs to be the best for Honda lawn mower GCV160. 

Among these factors include:

1. Size and Design

When choosing a spark plug for your GCV160 engine, the first thing you need to consider is the size and design of the spark plug. 

The GCV160 engine requires a spark plug with a 14mm thread diameter and a 3/8″ reach. 

Moreover, the spark plug should have a design that is compatible with the GCV160 engine. 

The spark plug’s design will determine how well it fits into the engine and how well it can transfer heat from the combustion chamber.

2. Material

Secondly, the material used in manufacturing the spark plug is also an important factor you shouldn’t neglect. But why? 

Spark plugs can be made of different materials, including copper, platinum, and iridium. Copper spark plugs are the most affordable but have the shortest lifespan. 

Platinum spark plugs are more expensive than copper spark plugs but have a longer lifespan. And Iridium spark plugs are the most expensive but also have the longest lifespan.

So you see the material you are going for would determine how effective the spark plug would be. 

But if you are on a budget, you can go for copper spark plugs, but be sure you will still have to change it in a short time unlike the other two.

3. Heat Range

Thirdly, you should also not ignore the heat rate of spark plugs. The heat range of a spark plug determines how well it can withstand heat from the combustion chamber. 

The GCV160 engine requires a spark plug with a heat range of 4. A spark plug with a heat range that is too low may cause pre-ignition, and may not allow the engine to start. 

4. Electrode Gap

Lastly, we have the electrode gap. This helps determine how well a spark plug can create a spark. And if you’d want to learn more about the spark plug gap, you can check our previous article where we explained it in detail here

However, the GCV160 engine requires a spark plug with an electrode gap of 0.028 – 0.031 inches. 

That’s to say if a spark plug with an electrode gap that is too wide or passes the recommended form it may cause misfiring.

While on the other hand, a spark plug with an electrode gap that is too narrow may cause fouling.
