Generally the do-it-yourself car owner will choose aftermarket auto parts over original equipment manufactured (OEM) because of the cost difference. Besides the difference in cost, there are other considerations that could add or detract from the actual value. Before making a decision on OEM vs. aftermarket it’s important to consider other factors besides the cost of the parts. The three main components for value comparison are
- cost
- quality
- warranty
Quality of OEM vs. Aftermarket Auto Parts
Most of the do-it-yourself car owners that choose OEM parts buy them because of the perceived quality versus aftermarket parts. After all how can you go wrong buying the original factory parts? In some instances OEM parts maybe a higher quality. But in many instances aftermarket parts maybe of like quality. In some instances they could exceed the quality of OEM parts.
To ensure that aftermarket parts are at least equal in quality, ask the retailer if they meet OEM specifications. Let’s use a do-it-yourself oil change as an example. When buying an engine oil filter, simply ask the retailer of the filter meets and/or exceeds the car manufacturers specifications. If the oil filter does not meet OEM specifications, it’s probably not worth saving a few dollars.
Comparing OEM and Aftermarket Parts Warranties
Although there are some exceptions, the majority of OEM parts carry a 12-month or 12,000-miles limited warranty. Aftermarket parts may carry a warranty that exceeds factory parts warranties. Some aftermarket parts may even carry a lifetime warranty, regardless of time and mileage. Before purchasing auto parts, ask the retailer about the specific warranty details.
A do-it-yourself car owner normally will not be reimbursed for the time spent to replace a part for the second time, if the part’s exchanged under the warranty. If the dealership replaces a factory part and it fails, both parts and labor are usually covered under the parts factory warranty.
An independent auto shop that replaces an aftermarket maybe not be reimbursed for labor under warranty, but in most cases will not charge the car owner for labor. It’s always best to ask the auto repair shop about their specific policy on parts and labor warranty. The repair order or invoice signed by the car owner should have a written statement concerning the warranty policy.
In a nutshell, don’t assume that OEM parts are more expensive than their aftermarket counterparts. To get the best value on auto parts, compare prices from the dealer and other retailers. Ensure that the quality is at least comparable to the original factory components. Look at the warranties when comparing OEM vs. aftermarket parts.
