OEM Spark Plugs vs. Aftermarket Options: What To Know

Many car owners become stuck in the perennial conundrum of choosing between original equipment manufacturer spark plugs (OEM) and their aftermarket counterparts. This seemingly small component is pivotal in a car's performance and efficiency.

If you're trying to decide between OEM spark plugs and aftermarket options, our guide below explains what you need to know about each.

Spark Plugs Explained

What are spark plugs, and what do they do? Plugs are the unsung heroes of your car's ignition system. They take on the task of igniting the air-fuel mixture in the engine's combustion chamber, setting your vehicle in motion.

There are several types of automotive plugs, varying in their materials and their expected lifespans. Their lifespans can range from 30,000 to over 100,000 miles, thanks to advancements like iridium and platinum tips enhancing durability and conductivity.

What To Know About OEM Spark Plugs

OEM plugs are those that the vehicle’s manufacturer (or a supplier they own) makes. One of the primary benefits of OEM spark plugs is that they ensure compatibility. OEM plugs also tend to have a reputation for quality, lasting as long as the originally installed set.

However, this quality and precision come at a price. OEM spark plugs are typically more expensive than their aftermarket counterparts, with some car owners reporting markup prices several times higher. Additionally, those seeking an enhanced driving experience may find OEM plugs less varied in performance.

What To Know About Aftermarket Spark Plugs

Aftermarket plugs cover many offerings, from standard replacements to performance-boosting options. Third-party manufacturers specializing in parts and accessories usually produce them, catering to a broader market and providing more options to customers.

Some aftermarket plugs are for performance and can improve acceleration, fuel economy, and power output. There are also economy plugs, which focus on affordability and a longer lifespan, although they trade performance for this at times.

Comparing OEM vs. Aftermarket Spark Plugs

Now you know the basics of OEM spark plugs and aftermarket options, but which is right for you? The choice comes down to cost, convenience, and your vehicle's specific needs. If you're content with your car's original performance and don't mind the incremental cost, OEM plugs might be the way to go. They work harmoniously with your engine and have a track record of quality.

However, if you're looking for cost savings or an improvement in performance and features, aftermarket spark plugs offer a viable alternative. While it may seem like a small change, the improved performance and fuel economy will pay dividends over the lifespan of the plugs and the vehicle.
