Advice from Subaru of Dayton for Drivers in Washington Township

Whether it’s for maintenance, repair, or performance, you’re faced with an important decision, go with genuine Subaru parts, or choose an aftermarket alternative?

While aftermarket parts are often promoted as a cheaper option, they can come with trade-offs in quality, fit, and long-term value. At Subaru of Dayton, we help drivers across Washington Township and the Dayton area make informed decisions for the health of their vehicles.


What Are Genuine Subaru Parts?

Genuine Subaru parts, also known as OEM (Original Equipment Manufacturer) parts, are designed and manufactured by Subaru specifically for your vehicle’s model and year. These are the exact parts your car was built with at the factory, which means they offer the best fit and performance possible.

They’re built to uphold Subaru’s strict safety and engineering standards and are backed by a factory warranty when installed by an authorized Subaru dealer.


What Makes Aftermarket Parts Different?

Aftermarket parts are made by third-party manufacturers. Some may be decent alternatives, but many are produced with less attention to detail, using lower-quality materials, and without Subaru’s testing standards. They’re made to fit a wide range of vehicles—not your Subaru specifically.

Here’s where issues often arise:

  • Inconsistent fit that may cause vibrations, leaks, or wear
  • Shorter lifespan due to lower material quality
  • Risk of triggering warning lights or interfering with electronic systems

Possible impact on resale value or warranty coverage

While they may cost less upfront, many drivers find themselves replacing aftermarket parts more frequently or repairing damage caused by improper fit.

Why Fit, Quality, and Warranty Coverage Matter

Even something as simple as a poorly fitted oil filter or brake pad can affect your Crosstrek, Outback, or Forester’s performance. In some cases, aftermarket parts can void your warranty or trigger unnecessary repairs, especially in critical systems like brakes, suspension, or electrical components.

With genuine Subaru parts, you can trust that:

  • The part was designed specifically for your Subaru
  • It has passed Subaru’s strict quality assurance tests
  • It is covered under your Subaru warranty

It will be installed by a certified technician who knows your vehicle inside and out

At Subaru of Dayton, our technicians use genuine parts because they’re built to last—and they help protect your investment.

When Are Aftermarket Parts Acceptable?

There are a few scenarios where aftermarket parts might be acceptable—such as non-essential cosmetic upgrades or hardware that doesn’t affect safety or performance. But we always recommend checking with a certified technician before going that route.

If your Subaru is out of warranty or you’re working with a specific budget, we’re happy to talk you through the pros and cons of each option for your situation.
