Whether you’re a seasoned mechanic or a weekend warrior just getting into small engine maintenance, understanding the ins and outs of spark plugs will take your engine performance to the next level.
This blog post will dive into everything you need to know about selecting the right spark plug for your Honda GX160, unveiling tips, tricks, and all the juicy details. Buckle up as we spark up this discussion!
What is the Honda GX160?
For those who might not know, the Honda GX160 is a compact, reliable four-stroke engine commonly found in various applications, from pressure washers to generators, lawn mowers, and more. It’s revered for its durability, fuel efficiency, and ease of maintenance. But just like any other engine, it requires proper care to operate effectively and efficiently. One of the critical components that contribute to its performance longevity is none other than our star today: the spark plug!
Functions of the Spark Plug
Before we delve into which spark plug you should choose, let’s take a moment to appreciate what this tiny hero does. The spark plug serves three primary functions:
1. Ignition: It ignites the air-fuel mixture in your engine’s combustion chamber, creating the necessary energy to propel your machinery.
2. Thermal Management: The spark plug helps to dissipate heat away from the combustion chamber, preventing pre-ignition and potential engine knock.
3. Engine Diagnostics: A worn or fouled spark plug can provide valuable insights into your engine’s health, often displaying signs of wear, burning, or soot buildup, which you can use to diagnose larger issues.
Types of Spark Plugs
When it comes to spark plugs, they aren’t all created equal. The type of spark plug you choose can significantly impact your GX160’s performance. Here’s a rundown of the most common spark plug types:
1. Copper Spark Plugs: These have a copper core that provides excellent conductivity. They’re typically affordable but wear out faster than other types, making them more suited for short-term use.
2. Iridium Spark Plugs: Sporting a fine-wire center electrode, iridium spark plugs provide superior ignition and longer lifespans, often lasting up to 100,000 miles. They’re a bit pricier, but that longevity makes them a worthwhile investment.
3. Platinum Spark Plugs: These are similar to iridium plugs in terms of lifespan and performance but can be less efficient. They are well-suited for engines requiring a good balance of cost and performance.
4. Extended Reach Spark Plugs: These plugs have a longer tip, providing a different flame propagation that can improve performance in specific applications.

How to Change the Spark Plug
Now that you’ve chosen the perfect spark plug, it’s time to change it! Don’t worry; you don’t have to be a rocket scientist to do this. Just follow these simple steps:
Tools You’ll Need
Spark plug socket or wrench
Ratchet wrench
Torque wrench (optional)
New spark plug
Anti-seize lubricant (optional but recommended)
Clean cloth or brush
Step-by-Step Process
1. Safety First: Ensure the engine is off and has cooled down completely. Disconnect the spark plug wire for safety.
2. Remove the Old Plug: Use the spark plug socket to carefully loosen and unscrew the old spark plug.
3. Inspect the Old Plug: Examine it for any signs of wear or oil fouling. If it’s worn out, it could indicate bigger issues.
4. Prepare the New Plug: If you’re using anti-seize lubricant, apply a tiny amount to the threads of the new spark plug.
5. Install the New Plug: Carefully screw in the new spark plug by hand to prevent cross-threading. Once snug, tighten it down with the torque wrench, ideally to the manufacturer’s specifications.
6. Reconnect Everything: Attach the spark plug wire back to the new plug. Ensure everything is secure.
7. Fire It Up: Give your engine a start, and listen for that sweet purr. Congratulations! You’ve successfully changed your spark plug!
Maintaining Your Spark Plug
Changing your spark plug is just one part of the overall maintenance cycle. Regularly checking your spark plug every season (or after a certain number of hours of use) will ensure optimal performance for your Honda GX160. Here’s how you can keep tabs:
Visual Inspection: Look for signs of wear, soot, or oil fouling.
Clean It: If the spark plug isn’t overly worn, you can clean it using a wire brush and proper cleaning agents.
Check the Gap: Use a feeler gauge to ensure that the spark plug gap is within the manufacturer’s specifications. Re-gapping may be necessary after cleaning.
Keeping Your Engine in Peak Condition
While a spark plug is crucial, remember that it’s just one part of your overall engine performance. To keep that Honda GX160 running like a champ, consider the following:
Oil Changes: Regular oil changes ensure the engine remains lubricated and runs cool. Opt for high-quality oil that meets Honda’s specifications.
Air Filter Maintenance: A clean air filter is vital for optimal airflow and engine efficiency. Be sure to check and replace it as needed.
Fuel Quality: Always use fresh, high-quality fuel in your engine. Old or contaminated fuel can lead to issues, including fouled spark plugs.
General Cleaning: Keep your engine clean. Debris can lead to overheating, so wipe down the exterior and check for buildup regularly.
