Today I had a Toyota Tacoma client pop in for an oil change. I see this truck about 4 times a year for service needs. The client keeps the truck clean and up to date on all service needs. A year ago the truck was in fender bender and the OE headlights got crunched. The client came in with some aftermarket headlight units and had us install them. I mentioned that the aftermarket plastics don’t hold up in the Arizona heat. The client said he saved a lot of money and they look fine to him. I installed them.
14 months later they look like poop! The plastics are hazed over, but not on the outside. This issue is on the inside, you can not fix an inside issue. You have to replace them again. The end story is the aftermarket parts are less expensive because they are a lower quality part. They kinda look the same, but upon close inspection, they are not.
Aftermarket parts are a problem. Many do not fit correctly, plus the over all finish work is not OE level and they do not last as long. When ever I can, I try to get the client to see the value in using factory parts when ever possible. This is not to say all aftermarket parts are poor quality. We use many aftermarket parts that match OE quality.
When we know that an aftermarket part is ok to use, we use them. We are always watching out for the client. In turn we do not want to use a part that will fail. If the aftermarket part can not meet our 3 year 36,000 warranty we do not want to use it.
We install 48% OE parts on clients cars.
The end game is to fix the clients vehicle correctly the first time and offer a repair that lasts.

Over loading a circuit with aftermarket equipment is the most common reason for a fuse to fail “blow out” In a home, you have 
circuit breakers that protect each circuit within the home.
I have found ear rings, small tokens, and paper clips stuck in the 12V power sockets. A direct short to ground will cause a fuse to fail instantly. 
Once you remove the junk from the socket the fuse can be replaced. At our service desk we offer free 12V socket to USB power adapters to plug into the open 12V sockets, just to prevent issues like junk or coins from getting into the socket and shorting the terminals in the socket
You do not want to use an inverter larger than 150 watts on a 15 amp fused circuit. Most basic 12V sockets only have a 15 amp fuse to power the socket, and its easy to pop a fuse with an inverter, cell phone, and GPS navigation all plugged in at the same time.
Filters protect your car from harmful debris that can cause damage to internal moving parts. The engine, and transmission need service regularly to keep them alive and happy. So what about you, the driver? Back in the mid 80’s some European car manufactures started adding air filters to the A/C system. Mercedes-Benz called it a particulate filter and it protected the A/C evaporator core from getting contaminated with hair, lint, leaves, and other nasty things that could get pulled into the air intake of the A/C system. It also protected the inside of the car from dust and oder. Most of all, the clean air was a benefit to the driver. European cars started using “Cabin Air Filters” first, around the mid 80’s. In the late 90’s I started to see them in high-end Japanese cars, and by the mid 2000’s almost all cars had some type of Air Filter added to the A/C system. The filter works great till, till it looks like the one in the picture. A filter can only do its job if it can catch and hold the dirt. This filter is past its way past its prime. looking at it, you might think it’s very old, but it’s only 3 years old, but the car is only used in town and in 3 years has only driven 7,000 miles.
