OE: Original Equipment: This part is either made by the car manufacture or is made by an automotive part supplier and is branded with the car manufactures logo and/or in the car manufactures box.

OEM Original Equipment Manufacture

OES Original Equipment Supplier

Car manufacturers do not make all their parts that they put on their vehicles during assembly or repair, they contract out to auto part manufactures to make parts for them. For the most part the car manufacturer makes the body, frame and major engine components the rest they ‘farm out’ to OEM/OES manufacturers. The car manufacturer provides the specifications to the OEM/OES manufactures for the parts they need. The OEM/OES manufactures the part to these specs, adds a logo and ships it to the car manufacture.

Bosch, Bilstien, Boge, Beru, Mann, ATE, to name a few, are all OEM or OES suppliers to the car manufacturers. They make parts from spark plugs to exhaust parts. The difference between OE and OEM/OES is mainly the OEM/OES usually don’t have the car manufactures logo, but they are the same exact part. Sometimes the logo is ground off the part by the OEM/OES company so as not to affect there contract with the car manufacture. Same part coming off the same assembly line as the OE part does.

The OEM/OES parts are less expensive because they do not go through the car manufactures part system. Every time an OE part goes through a depot, warehouse, dealer, there is a little more money added to the cost of the part. This is the major reason that OE parts cost more. OEM/OES do not go through this procedure, our buyers get them directly from the manufactures, keeping the prices down.

Aftermarket: aftermarket parts are just that, aftermarket. They are not made by the car manufacturers. They can be made by one of the original equipment manufacturer companies or by a completely different manufacturer. The main difference is they are not made completely to the car manufacture specifications. This is not always bad. One example is Bilstien. They are an OEM/OES supplier, but they offer aftermarket parts also. There HD struts/shocks are original equipment, but their Sport struts/shocks and suspension kits are not made to OE specifications, better but not OE, so it’s now an aftermarket part. Another example is the Stewart EMP BMW water pumps. Stewart EMP is NOT an OEM/OES manufacturer but the pump they make is better and stronger than OE. It is an aftermarket part but a better part altogether.

But still another example of an aftermarket BAD part is a counterfeit part. Counterfeit part manufacturers use backward engineering to get the specifications of the part without paying the car manufacturer. And almost all the time these parts are made with very low quality components. Sometimes these parts are very hard to identify because a lot of emphasis is put on the look and feel of the part and not what it is made from. One way to identify an counterfeit part is its unbelievable low price, the old adage you get what you pay for fits here. The best way to avoid these cheap low quality parts is to purchase your parts from a reliable source, one that offers a warranty and return policy.

Automotive Services

Most of us rely on a mechanic to tell us what is wrong with our vehicle, but how do you know you are getting a good repair job at a fair price? There are a few things you should look for when you need automotive services.


When you take your vehicle in for repairs, you should see certifications hanging on the wall. You want to take your vehicle to a garage that participates in certification courses on a regular basis and keeps up on new car features.

In particular, make sure your mechanic is up-to-date with his or her Automotive Service Excellence (ASE) Certification. The National Institute for Automotive Service Excellence is the gold standard among car manufacturers and mechanics. To receive the certification, mechanics must have a high score in one specialty area (engine repair, brakes, suspension, etc.) and two years of professional experience. A service center with an ASE blue seal signifies that 75 percent of employees working at that establishment are ASE certified. If your auto shop is missing an ASE sticker, do not get your car serviced there.

Quality Auto Parts and Services

Another sign of good automotive service is the use of quality parts. It can be tempting to save a few dollars on off-brand parts when your repair expenses start adding up, but a quality repair shop will tell you that you aren’t really saving anything. Quality parts will last longer, which means you won’t have to replace them as often. Safety could also be an issue with used or inferior car parts. You don’t want to put yourself or your passengers in jeopardy over a couple dollars of savings.

When you find good automotive services, you will save money. All shops should provide these routine auto maintenance services:

– Oil change
– Brake repair
– Tire realignment
– Inspections

In addition to providing the usual array of services, good mechanics will give you a fair price. They won’t charge you for the little things like topping off your fluids or checking the pressure in your tires, and they are more interested in keeping your car running right than charging for air.

Shops that have good automotive services look out for their customers. They know that business is based on developing trusting relationships. They take the time to check for basic safety hazards while your car is in the shop, alert you to important maintenance items that are overdue, and try to educate you about the vehicle you drive.

Great Customer Service

Good shops also put customer convenience first. They realize it is difficult for you to function without your vehicle. They do their best to complete the work and get you on your way quickly. If you have to wait for your car to be serviced, they make the waiting area comfortable with complimentary coffee and snacks, television, and Wi-Fi. Quality shops open early so you can drop your vehicle off before work and stay open late for you to pick it up.

Commercial And Automotive

You might be surprised to learn that there are different types of locksmiths around. This is essential especially for those who want a more specialized service. Residential, commercial, automotive and forensics are the types of locksmiths that are accessible although the forensic ones are rare as they usually work with investigative agencies or law enforcement agencies.


Residential locksmiths are experts when it comes to making the home safe and secure. As most homes have the regular locks installed near window frames, it might compromise the safety of the family. These experts can install a double cylinder lock that needs a key inside for the door to open to give extra security. Aside from this base-knowledge they can also re-key locks as well as have them replaced in such a way that these are not easily tampered. They can also do entry gates, screen doors, sliding as well as emergency services.


A commercial locksmith specializes in locks that are manufactured for business purposes. Examples would be installation of panic bars, replacing locks in file cabinets, installation of automatic door closer, safe/vault installation as well as installing a master-key system. Panic bars are especially important as they would provide workers a means to exit the building premises in case of emergencies.


Automotive locksmiths are the ones that you go to if you ever need a spare car key or want a replacement when you’ve lost the original car key. These experts can help automotive owners in choosing the right type of car keys that would best suit their needs. Most automotive locksmiths are familiar with transponder car keys and can also do re-programming at a lower price compared to the same service that car dealers offer. Aside from transponders, they can also unlock cars, change or replace ignition locks, provide laser cut keys and even offer lock services for high security vehicles.


In choosing the locksmith that would best suit your need(s), it is important to deal with a company that is licensed and has done background checks on their employees. This is to make sure that the company that you would be transacting with is legal and since some items in the house might be valuable or important documents are inside vaults or safes, one is assured that the person they are dealing with is someone who they can trust. Consider talking with someone who knows a reputable locksmith especially if you’ve just moved in or purchased a new home or office.
