Your Subaru, with its renowned reliability and performance, deserves the best care possible. One often-overlooked component that plays a crucial role in your engine’s health and efficiency is the spark plug. These tiny but mighty devices ignite the air-fuel mixture in your cylinders, powering your vehicle. Choosing the right spark plug can significantly impact your Subaru’s performance, fuel economy, and overall lifespan. So, what brand of spark plugs does Subaru use? The answer isn’t as straightforward as you might think.
Subaru, like many automakers, utilizes a variety of spark plug brands depending on the specific model year, engine type, and even trim level. This can make it confusing for owners trying to find the perfect replacement for their vehicle. This comprehensive guide will delve into the world of Subaru spark plugs, exploring the brands they commonly use, the factors influencing their choice, and how to determine the right spark plugs for your Subaru.
Understanding Spark Plugs
How Spark Plugs Work
Spark plugs are essential components of an internal combustion engine. They generate the high-voltage electrical spark that ignites the compressed air-fuel mixture in the combustion chamber. This controlled explosion pushes the piston down, generating power that drives the vehicle.
Types of Spark Plugs
Spark plugs come in various types, each designed for specific engine requirements. Common types include:
- Copper Core: These are basic, affordable plugs known for good heat dissipation.
- Platinum: Platinum-tipped plugs offer longer lifespan and improved performance at high temperatures.
- Iridium: Iridium-tipped plugs provide the longest lifespan and are often found in high-performance engines.
Subaru’s Spark Plug Preferences
Original Equipment Manufacturers (OEM)
Subaru typically uses spark plugs from reputable OEM suppliers like NGK and Denso. These manufacturers are chosen for their quality, reliability, and compatibility with Subaru engines.
Specific Brands and Models
While NGK and Denso are common, Subaru may use other brands depending on the model year and engine. For instance, some older Subarus might use Bosch spark plugs. It’s essential to consult your owner’s manual or a reliable online resource to determine the exact spark plug specifications for your vehicle. (See Also: What Is the Best Type of Spark Plug to Use?
