It's really expensive to perform the level of quality control required for OEM, so aftermarket companies don't always do it. This is true even for parts that are made by the same company.

Example, widget A has a very specific length requirement. 100% parts sent to OEM are checked for length, and the bad ones rejected before they are sent to the OEM. Aftermarket they don't check 100% if it's too expensive. They might check 10%.

In addition to that, there are teams of personnel at the OEM to check parts before they are shipped to the dealer.

Make your own decision, aftermarket parts are not bad, but you have a higher chance of getting a quality, trouble free, part by going to the dealer.
Not to rain on your parade but from seeing what happens with controls from manufacturing. It's still possible for out of tolerance **** that should be inspected 200% get to customers. F-15's are not excluded here, since a coworker's wife was dealing with this issue last fall. Take the lovely oem "blue" fliter that is being recalled because of a leaky gasket. I've seen it in all the shops I've been in, you get low quality people who don't get a **** and don't check tolerances they should be. A lot of which trickles down to laziness or incompetence. I've even seen parts with inspected tolerances that were out get the approval and go out the door.

Done with my working with monkeys rank.
