Types of Auto Parts Numbers
OEM Numbers
OEM numbers are essential for anyone looking to replace a part with an original manufacturer’s component. Each part has a specific number assigned by the manufacturer, ensuring that the replacement will fit perfectly. These parts are often more expensive, but they guarantee quality and longevity. Websites like www.rockauto.com and www.napaonline.com are excellent resources for finding OEM parts.
Aftermarket Numbers
Aftermarket parts provide an alternative to OEM options, often at a lower price. These parts are manufactured by third-party companies and can vary in quality. It’s important to research the brand and read reviews before purchasing aftermarket parts. Retailers like www.autozone.com and www.partsgeek.com offer a wide range of aftermarket options.
VIN
The Vehicle Identification Number is a 17-character code that uniquely identifies your vehicle. By utilizing the VIN, you can ensure that you’re purchasing parts that are designed specifically for your car model. Many online retailers allow you to enter your VIN to filter parts, making your search much more efficient.
Interchange Numbers
Interchange numbers are crucial for finding compatible parts across different brands. This is particularly useful for older vehicles where OEM parts may no longer be available. By understanding interchange numbers, you can find suitable replacements that fit and function correctly.
SKU
The Stock Keeping Unit is a number used internally by retailers to track inventory. While SKUs may not be as useful for consumers, they can help you locate parts more easily in a store or online. If you’re shopping at a local store, knowing the SKU can expedite your search.
How to Use Auto Parts Numbers Effectively
