Buyer’s Guide
Need some guidance with buying your replacement spark plugs, our buyer’s guide can help you there!
Compatibility
The first thing you need to determine is whether the spark plug is compatible with your vehicle.
If the plug is not compatible, then you aren’t going to see the right results. Incompatible plugs will not fit properly and often leave gaps, which can cause severe issues down the line.
Thankfully, choosing the compatible plug is not a game of guesswork! Most manufacturers allow you to check the plug will be compatible by entering your vehicle’s model number.
You will be told whether the plug is compatible or not then. So be sure to have your vehicle’s model number at the ready when searching for your spark plug!
Materials
As with most electrical devices, the performance of your spark plug relies on good quality materials being used.
The structure of the spark plug should contain metal to ensure excellent strength and longevity.
Platinum or iridium tip spark plugs are some of the most popular and top-quality spark plugs on the market. Be sure to check the electrode before purchasing to ensure the strength is appropriate.
Changing Intervals
Unfortunately, no spark plug will last forever, so you must check the estimated service interval on the spark plug.
The estimation is usually given in miles and indicates at what point your plug will need maintenance or be replaced.
As a general rule, opt for spark plugs that have between 60,000 to 100,000 miles of the estimated service interval.
It is worth noting that these estimates are only estimates. You can get less or more miles depending on your driving, the same you would with fuel.
How hot can it go?
Another vital factor to consider is the melting point of your replacement spark plug. Your engine will be hot as soon as it starts up, and your plug needs to be able to handle these high temperatures.
Platinum tips again are a strong choice to consider. They usually have a high melting point and withstand bursting.
Look out for these plugs and pay attention to their melting points. After all, there’s no point replacing the plug if it is going to melt straight away, is there?
Look out for plugs that are advertised as corrosion resistant too. These will have used materials or coatings that will protect the plug’s inner components from any damage. It is always worth checking out customer reviews to see their thoughts on the performance of the plug.
Easy to install?
When purchasing your spark plug, having one that is easy to install is always a bonus! Thankfully, most spark plug replacements are straightforward to install.
Keep an eye out for those listed as easy to install or plugs that have been praised for being easy to install by other customers. These are the best options for people who have never changed a spark plug before.
As with any electrical component, take extra care and ensure you have all the necessary protective equipment. There is also a wealth of tutorials available online should you run into any difficulties.
How much?
When it comes to replacement spark plugs, the price can vary depending on the brand and materials used. That does not mean you need to plan a bank heist to get the correct spark plug for you and your needs!
Be sure to set a clear budget when purchasing your spark plug and stick to it as closely as possible. Consider the materials that you want and how many miles before service when setting your budget.
Remember that you don’t need a high budget; there is a good quality replacement spark plug to suit every budget!
Warranty
As with any electrical component, checking the warranty before purchasing your spark plug is a good idea. You want to be sure that should anything happen; you will be protected.
Usually, electrical components will come with a 12-month warranty. This information is generally displayed in the product description or listed in the manual.
It is always worth checking in the warranty section what could void your warranty. Often changes to the internal components by yourself can void warranties, so be sure to check before undertaking any work!
