In case you don’t want to read the shopping guide, here are the most reliable brands of spark plugs right now:
LOOK INTO owner´s manual
The first step in our shopping guide is to take a look into 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. Here is our guide to changing the spark plugs on your generator, check it out for detailed step by step instructions & videos.
Also, 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 replacements spark plugs for your device.
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 other at the tip of a plug – see the image below).
As already mentioned, you can find this measure in the Owner’s Guide or Manual.
Based on our experience, the vast majority of portable generators need a spark plug of size 0.028″ – 0.031″ (0.7 mm – 0.8 mm). However, the gap your spark plug needs to have may differ.
That is why you need to always double-check it.
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.
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 with regards to choosing the right spark plug.
- Mentions of compatible brands
- Specific models for each brand
- Allowed material of electrodes
Just keep in mind that if you decide not to follow recommendations in your Owner’s Manual, you can void the warranty of your generator.

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 personally believe that all these are excellent brands. They all have been recommended in various user manuals to 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 a 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 at 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 hurricane season starts, spark plugs may become hard to get in general.
