Are you looking for new spark plugs for your generator but have no idea how to choose them?
I have great news for you! Our team here at Generatorist has helped over 600,000 visitors find information about generators and we will help you as well.
You will find tips on what to consider when making your decision, as well as a list of reliable brands and a chart of popular generators with corresponding spark plug types and sizes.
Additionally, we will give you a list of links where you can download the Owner’s Manual for popular generators, and we have created guides with specific spark plug types and gap sizes for the most common brands.
Let’s begin with the tip number 1:
LOOK INTO The owner’s manual
The first step in our shopping guide is to take a look at the Owner´s Manual you got with your Generator. There, you will find every piece of information you will ever need, so don’t throw it away.
From our personal experience, the info about spark plugs is provided in the maintenance section. Usually, there is a specific brand and a model number stated there.
We have created detailed guides with specific spark plug types & gap sizes for the most popular brands like Predator, Champion, Generac, Honda, Yamaha, Pulsar and Ryobi as well. Go ahead and find the ideal spark plug for your generator.
Feel free to mention the brand and model of your generator in the comment section and we will get back to you with the info about the best replacement spark plugs for your device.
We also have a list of links below this guide, where you can download the Owner’s manual for the most popular generators on the market.
MIND THE REQUIRED GAP
One of the few features you need to pay close attention to while choosing the spark plug for your generator is the recommended gap between the two electrodes (one curved and the other one at the tip of a plug – see the image below).
As we have already mentioned, you can find this number in the Owner’s Guide or Manual.
The most common generator spark plugs specifications are as follows:
- Gap size: 0.028″ – 0.031″ (0.7 mm – 0.8 mm)
- Socket size: 5/8″ (16mm) or 13/16″ (21mm)
Based on our experience, the vast majority of portable generators need a spark plug with a gap size of 0.028″ – 0.031″ (0.7 mm – 0.8 mm). Keep in mind that the spark plug gap for your specific generator might be different.
That is why you always need to double-check it in your manual.
You should also have a 5/8″ (16mm) or 13/16″ (21mm) socket & ratchet at hand in case you want to replace the spark plug by yourself.
Don’t worry, we have the data and specifications for the most popular generators below our guide.
You need to realize that if you insert a different type of spark plug than recommended, you may cause significant damage to your engine that is very expensive to fix.
That is why you should always get the correct model and type for your generator.
Follow the RECOMMENDATIONS
Not only will you find the information about required gap measurement in the maintenance section of your Owner´s Manual, but you will also discover other recommendations about choosing the right spark plug.
These include:
- Mentions of compatible brands
- Specific models for each brand
- Allowed material of electrodes
Just keep in mind that if you decide not to follow the recommendations in the Owner’s Manual, you can void the warranty of your generator.
For example, here are the best spark plugs for Honda generators:
- Honda 98056-55777 Spark Plug CR5HSB – Fits EB2000i, EU1000i, EU2000i, EX700C, EB2000, EU1000 and EU2000 models. Genuine OEM Honda part. Replaces MPN 98056-55757.

GO FOR QUALITY NOT PRICE
Last but not least, you should never try to save on spark plugs for your generator. Preferring low price instead of a high-quality product may cause a lot of worries later.
Instead of trying to save a couple of bucks, rather invest a little bit more into high-quality spark plugs made by reliable brands, such as:
- ACDelco (check the products here)
- NGK (check the products here)
- BOSCH (check the products here)
- AUTOLITE (check the products here)
- Champion (check the products here)
- Torch (check the products here)
- Denso (check the products here)
We believe that all these are excellent brands. They all have been recommended in various user manuals for portable generators.
If you want to get your supply of high-quality spark plugs for a decent price, then take a look at Amazon.com deals.
Just keep in mind that individual generators may need different models of spark plugs.
Ask for professional help
Are you worried that you have chosen the wrong spark plug and that you may damage your engine? If you are not sure that you will choose the right spark plug for your generator, then ask an expert for help.
It is better to admit you need help than to cause significant damage to your engine.
Just make a call to the local distributor or retailer of your brand of generator and I bet they will gladly help you.
You can find the local authorized dealers on this website or you can mention the brand and model of your generator in the comment section below and we will do our best to help you.
Have spare plugs at hand
Our last advice is to get at least a couple of spare spark plugs as soon as possible. Because this spare part is not expensive, and will not deteriorate if stored correctly, you can afford to get at least a couple in advance.
Once you are out of power and your spark plug gets damaged, you may have a hard time finding the correct model in your area.
Also, once the hurricane season starts, spark plugs may become hard to get in general.

Is it a good choice to upgrade from a regular OEM spark plug to iridium for my portable generator? If so, how do I cross-reference these plugs? All my searches only suggest other brands but none for iridium. What are your thoughts?
Hello Mike,
I am sorry for responding to your comment with such a delay. To answer this question, I would need to know the brand, and version of your generator and a type of recommended spark plug (I can check that out in Owner´s Manual once I know other info).
Only then I can provide you with an answer as not all machines are suitable for Irridium plugs.

What is the best spark plug for a Champion Inverter generator that has a Natural gas conversion kit installed? Do all spark plugs “fire” the same?
Thanks!

Can you tell me what replacement spark plug I should purchase for a “category five powered by champion” 5000 peak watts/4600 running watts portable LP generator. The manual recommends the brand “green power” but I can’t find those anywhere. It also says it comes equipped with a three-quarter inch long reach plug (19 mm) and the spark plug gap is 0.7 – 0.8 mm ( 0.028 – 0.031 in.). Thanks for your help, much appreciated!
What spark plug would a Briggs and Stratton Storm Responder 6250 (model 030729-01) need replaced with. The one referenced in owner’s manual (797235? isn’t on their website to purchase
Replace with 798615.
I have a Generac whole house 11,000 KW generator and the manual offers, naturally, their specific spark plug. I would like to obtain an upgraded generic plug, but am not able to find any reference to a market available replacement plug.
Any help would be greatly appreciated.
Thanks, Dale R. Snyder
Sir
I have an Onan BGE RV generator i want to pad mount it at the house and run it off of natural gas.
It had NGK R V-power TR4 plugs in it. Is there a better plug for NG?
Thanks,

I have a old (40 yr+) Robin generator LG201 engine type EY20w and probably have never replaced the plug. Generator has always bailed me out when required until now and I want to start resolution by replacing plug Champion L86C but don’t know what the proper current plug is
