Hey everyone! I was wondering if this forum has a list of parts that should be OEM and which parts you can go aftermarket on? Or, does Scotty have a video about this topic?
I think that all depends on the vehicle and particular part. For instance, normally I would say you can go aftermarket Starter, but a toyota 4.7 engine is harder to replace it than most, and would be best to go oem for longevity.
Some that I go aftermarket, alternator, starter, suspension but KYB only. Things like control arms, Tie rods, bearings. Brake equipment, rotors, calipers, Brake pads.
Some that are best to go oem, sensors like O2 and maf, AC compressor typically unless you are doing it all yourself maybe. Ignition Coil packs.
Oem is often best, but the cost can be so much higher it is worth it going aftermarket.
That's a few things.
@nlord good list. One change for me would be alternators, both local mechanics I recommend won't install anything but OEM.
@hixster yeah that is an overall good rule. The one exception I made after researching, was Remy Alternators and starters. They make OEM ones, and for my Pontiac vibe, the specs, and even the pic with sticker on it is identical to an AC Delco oem alternator, I think it was my vibe at least. Looks to be exactly the same. For my cars, I pretty much can't get a new Denso alternator anyway unless it is re-manufactured, I prefer not to get a re-manufactured one as it is a gamble, depending on who did the work.

Generally speaking, my preference is the genuine part or the OE manufacturer for the genuine part. For example, Toyota or Honda, I would use Aisin or Denso parts. (Look out for slight mis-spellings, as aftermarket brands may try to resemble other more recognizable names.)
But I get it, sometimes genuine or OE are expensive.
So if it is a vital component of a car, I will usually go genuine or OE. If it is a non-vital component with easy access, I may try afternmarket, but with trusted brands first. If it is a non-vital component in a super hard place to reach, I will probably go genuine or OE. I will also go aftermarket if it is a trusted brand and an upgrade for the car.
@kaizen so something as easy to get to as an engine air filter?
For air filters, I usually either go genuine from dealer or try to stick to the name brand aftermarket that has similar or better quality, that you can get at the auto parts store depending on pricing or coupons.
YouTube “Project Farm Air Filter”. This guy does tests on various brands.
