Nowadays the first place we head for finding auto parts is the internet but what seems like a good deal may not be so good in the long run. Dealerships make the statement "no aftermarket parts will work no matter what you do" this of course is a lie. There are plenty of good aftermarket parts that are great replacement parts from many companies out there. Many times the dealership themselves will be selling parts that are considered aftermarket. All auto parts have a failure rate associated with them...from new OEM and aftermarket to Remanufactured parts they all have risks. Every part has a certain % of the parts that will fail no matter who does the install. That said there are steps that can be taken to avoid failures not related to this percentage.
Having replacement parts installed properly is a huge factor in the life of the part. While your mechanic down the street may be a good guy and your friend you have known of many years, it does not mean he knows every repair. Over the past decade alone the technology in vehicles has gone from being so basic that a child could build them to the point that a rocket scientist would have to take a step back. While your mechanic may have been working on cars for 30 years think of what a 1981 Buick really has in common with a 2012 Mercedez Benz.
The quality of an installed part plays a huge impact on the life of the part but it is not the only factor. Most parts now are built in Asia including many OEM parts and a lot of people will say "that's cheap Chinese crap" but the truth is you can buy cheap or quality from anywhere. What a part buyer will need to pay attention to is the quality standards of the seller and the quality of the installer. If a turbo is installed incorrectly or all the prep work is not does not matter if the unit is the best that Borg Warner has to offer it will fail. DO the research and read the reviews of a part or a company, if they sell cheaply made parts then they wont be around long.
