There are a lot of choices when it comes to spark plugs, and it cannot be easy to know which ones are best for your Scion xB. In this post, we’ll look at some of the finest alternatives accessible and assist you in choosing the ideal plugs for your car. We’ll also discuss the advantages of utilizing performance spark plugs over stock spark plugs.
The best spark plugs for your Scion xB depend on what you’re looking to get out of them. If you’re looking for OEM replacements, then you’ll want to go with Denso Spark Plugs. These are designed to provide long life and excellent ignitability. They also resist fouling and have a low electrode wear rate. For performance applications, we recommend NGK Spark Plugs. These plugs offer better ignitability and fuel efficiency. They also have a higher melting point, which helps to prevent pre-ignition and engine knock.
Remember to gap them correctly, no matter what spark plugs you choose. Incorrectly gapped spark plugs can cause many problems, including poor fuel economy, decreased performance, and starting issues. You can find the correct gap for your xB in your owner’s manual.

Should I Replace All My Spark Plugs At Once?
Yes, it is better to replace them all at once.
Replacing all your spark plugs at once is always the best option. You should replace them as soon as you notice any wear or tear to avoid an increased risk of car damage. Replacing them one-by-one is likely to lead to inconsistent performance, so replacing them all at once will give you a much better power source for your engine.
It is important to replace your spark plugs in a timely manner because they can cause your car to stall or not start at all if they are too worn out.
