Who Makes Toyota Spark Plugs? (SOLVED)

When it comes to the performance of your Toyota, spark plugs are a crucial component that should never be overlooked. These small but mighty parts provide the necessary spark to ignite the fuel in your engine, helping your car run smoothly and efficiently. But who makes the spark plugs that power your Toyota? In this article, we’ll delve into the world of Toyota spark plugs and explore the companies behind them.

Toyota OEM Spark Plugs

To start with, let’s talk about Toyota’s original equipment manufacturer (OEM) spark plugs. These are the spark plugs that come pre-installed in your Toyota when it rolls off the factory floor. Toyota uses a variety of different companies to manufacture their OEM spark plugs, depending on the specific model and engine type.

Some of the most common manufacturers of Toyota OEM spark plugs include Denso, NGK, and Bosch. Denso is a Japanese company that has been making spark plugs since 1959 and is one of Toyota’s biggest suppliers. NGK is another Japanese company that has been making spark plugs since 1936 and is known for their high-quality products. Bosch is a German company that has been making automotive parts for over 100 years and is a trusted supplier for many car manufacturers.

Aftermarket Toyota Spark Plugs

While Toyota OEM spark plugs are designed specifically for your car and engine, there are also aftermarket options available. These spark plugs are made by third-party manufacturers and can often offer improved performance or longer lifespan compared to OEM spark plugs. However, it’s important to note that aftermarket spark plugs may not be compatible with all Toyota models and could potentially cause damage to your engine if not installed correctly.
