How to Identify OEM vs Aftermarket Parts for Your Acura
When replacing parts on your Acura TL, TSX, or RL, one of the biggest decisions is choosing between OEM and aftermarket parts. But how can you tell the difference—and which one is right for your ride? Let’s break it down.
What Are OEM Parts?
OEM stands for Original Equipment Manufacturer. These parts are made by or for Acura and are the exact same components your car came with from the factory. They fit perfectly, meet Acura's quality standards, and typically come with a manufacturer warranty.
What Are Aftermarket Parts?
Aftermarket parts are made by third-party companies and are designed to replace OEM parts. While some match OEM quality or even outperform it, others can be poorly made or incompatible. It’s important to know what you’re buying.
How to Identify OEM Parts
- Branding: OEM parts often have Honda/Acura logos, part numbers, or the brand “Denso,” “Bosch,” or “Nissin” (OEM suppliers).
- Packaging: Genuine OEM parts come in Acura-branded packaging with part numbers printed clearly.
- Fit & Finish: OEM parts typically have better build quality, cleaner welds, and exact matching hardware.
- Price: OEM parts are usually more expensive due to quality control and branding.
- Dealer Verification: You can verify part numbers through an Acura dealer or trusted OEM database.
How to Identify Aftermarket Parts
- No Acura Branding: No logos or part numbers tied directly to Acura or Honda.
- Generic Packaging: Plain boxes or non-OEM labels (may include “Direct Fit” or “Replacement Part”).
- Fit Issues: You may notice slight differences in size, connection points, or durability.
- Third-Party Manufacturer: Brands like Dorman, Beck Arnley, or generic eBay/Amazon parts are usually aftermarket.
Pros and Cons
| OEM | Aftermarket | |
|---|---|---|
| Fit | Perfect factory fit | May require adjustments |
| Cost | More expensive | Typically cheaper |
| Warranty | Usually included | Varies by brand |
| Availability | Dealer or specialty stores | Widely available online |
Which Is Better?
If you want exact fitment and long-term reliability, OEM parts are often worth the extra cost. If you're on a budget or customizing your ride, high-quality aftermarket parts can be a great alternative.
