“To save money and time while enjoying maximum comfort,” is a common response from 50cc scooter riders when I ask why they ride a 50cc scooter rather than a 100cc, 125cc, or higher, or even why not cycle.

In the field of spark plugs, X-PRO is a tough competitor. We tested their A7TC spark plug in our 50cc variant, and it did not disappoint.
Usually, this A7TC series is made for 50cc 4-stroke engines. But it can easily fit into any 50cc engine, as we found in our test.

Ignition is what a spark park does, and proper and rapid ignition is what we need and expect from a branded spark plug. Interestingly, this C7HSA model spark plug by NGK provides it all.
This spark plug is a standard quality spark plug. Its wire measurement to the ground electrode, is all set to perform smoothly.
Its core material is copper, which is also famous for its high melting point. This provides a good heat rate and ensures rapid ignition.

Importance of Choosing the Right Spark Plug
To know the importance of the right spark plug, first knowing the engine is a must. We know the engine is a visible converter that converts power to motion.
Here, power means heat and pressure. Basically, a compressed air-fuel mixture produces the power that converts into motion. Here, in the production of power, the spark plug plays a key role as a motivator.
The air and fuel combination in the combustion chamber is ignited by the spark plug. This ensures that the vehicle’s engine has adequate power to start.
Now coming to the main point. Every engine capacity is different and it’s identified by the engine’s cubic capacity or CC. The higher the cc, the higher the conversion of power to move.
That indicates the demand for ignition is not always the same. Small engines like 49cc or 50cc require a spark plug of different sizes, gaps, and capacities as it needs less ignition than the higher one.
That’s why choosing the right spark plug for your engines is important. Especially, when you are looking for a 50cc scooter spark plug.
Copper, Iridium, Or Platinum: Which Spark Plug Is Better?
Well, there is sharp competition among these three types of spark plugs. Let us show you a comparison so that you can pick the better one!
| Comparison Base | Copper Spark Plug | Platinum Spark Plug | Iridium Spark Plug |
| USER DEMAND | Mostly Used | Less than Copper spark plug due to high price | Less than Copper spark plug due to high price |
| Price | 3-12$ | 5-18$ | 8-15$ |
| Heat Production | High | Medium | Medium |
| Heat Control | Low | High | High |
| Misfire Rate | Little | Very low | Not |
| Life Span | Poor | Higher than Copper spark plug | Higher Than Platinum spark plug |
| Firing Efficiency | Average | High | Higher than Platinum |
| Availability | Most | Not available everywhere | Not always available everywhere |
If you see the comparison chart, copper spark plugs have the highest demand but less efficiency than platinum and iridium spark plugs. But the platinum and iridium spark plugs have less demand due to their high price and limited availability.
Additionally, copper spark plugs are less efficient than platinum and iridium spark plugs. And also, the lifespan of the copper spark plug is less than that of platinum, and the Iridium spark plugs are longer than the copper and platinum spark plugs. Now, choose wisely which one is superior.
One-Line Suggestion
If you notice all 5 spark plugs, you will notice a common thing: the plug seems the same. That means there are not many differences between them, so you can choose yours confidently.
How We Made This Review
For a long time, we, a team of mechanical, technical, and marketing experts, along with professional riders, did our research for a long period. During the research, we applied several spark plugs from various brands like NGK, X-PRO, ACDelco, Champion, and FVRITO to our 50cc scooters. And finally, after investigating all the required factors, we chose those 5 spark plugs each as the best 50cc scooter spark plug.
Doubts To No-Doubt
There are some factors to determine if your spark plug is bad or not. It’s not fit the same, but if your engine has poor fuel economy, unusual noises, hard starting, and poor performance, then you can consider that your spark plug is bad.
Powerful engines like 212cc, 250cc, and 500cc need a spark plug change after every 30 thousand to 50 thousand miles of running. But in a 50cc scooter engine, you can change the plug after 80 to 100 thousand miles of running.
It’s a very common misconception that changing the spark plug increases engine power. Well, it’s not like that. Actually, new spark plugs don’t increase the power, but rather improve the performance, smooth the starting, and increase the fuel economy.
Yes, you can replace the spark plug by yourself. Just use a spark plug wrench, a spark plugs gapping tool, and a cloth. Use the wrench to remove and reinstall the old and new spark plugs. Use the gapping tool to measure the gap and that is how you can replace it by yourself.
Not always, but if you’re changing your spark plug after a long period, then changing the spark plug wire is a must. Otherwise, a new spark plug cannot support the improvement of the engine’s performance alone.
Final Words
Our task is complete to guide you in choosing the best spark plug for 50cc scooter. Now, it’s your turn to make a choice for your daily road partner.
However, we recommend you think about the AloneGoer A7RTC Spark Plug. It’s already in our top pick.
One last suggestion, do change your scooter’s spark plug after every 80000 to 100000 miles even less than that. It will keep the engine performance up.
