Performance vs OEM Parts: Comparison

Assume you need a new brake pads, alternator, or some other replacement component. At the products counter, you have many options, ranging from low-cost economy parts to higher-priced performance parts. We’ve seen how aftermarket products are just as high quality as original equipment manufacturer (OEM) parts and are even the same sometimes. Today, however, we’ll look at why there’s a price gap for performance parts, and why you may want to buy the high-performance improvements rather than save money with budget components.


So, you just discovered that your Ford Mustang’s alternator is failing. When you check online, you can easily find 130 amp and 200-amp models for the same vehicle, each with a different price. Which one should you choose?

That is dependent on your requirements. You can’t exaggerate the amps here, so don’t think about it. If you have an 85 amp or 300-amp alternator, the electrical components in your car can only receive the power they need to function.

If you’re doing a lot of slowing down in city traffic, such as an Uber driver, a relatively high alternator will help avoid battery undercharging. If you like off-roading, the additional lights, winch, and other gadgets put more strain on the power system, so go for a high output.

Finally, why risk undercharging if you’re changing the alternator in a normal daily driver? Get the updated alternator to completely charge the battery and power any future attachments you might add.

Rotors and Brake Pads

We’ve already discussed the variations between brake pads, so let’s take a look at OEM and performance brakes. Economy brakes and rotors are engineered to meet the bare minimum of safety standards while being as inexpensive as possible to manufacture. This is clearly observable in their stopping efficiency, tolerance to brake fade, and overall durability.

Performance brake rotors are built to withstand rough driving, as well as racetrack violence and heat. As a result, many of them have cryogenic treatments in the machining operation, as well as slotted and/or drilled rotor surfaces that keep them cool during prolonged use. You can get these performance car parts online nowadays.

Exhaust and Catalytic Converter

When it comes to can the power of a vehicle, one of the first changes that owners make is replacing the exhaust system. Performance exhaust components are designed for better flow and less pressure drop than OEM parts, allowing the engine to produce more power because it does not have to work as hard to drive the spent exhaust gases out of the system.

If your catalytic converter dies, you must replace it immediately to avoid further damage. If you have little interest in vehicle efficiency and no plans to change your daily driver, save money by purchasing the OEM catalytic converter. They’ll meet pollution standards at a fair cost.

Oil Filters and Oil

There are some distinctions between traditional and synthetic oil, as well as distinctions between supermarket brand and more expensive performance brands. 

There is also a notable change in oil filters. On the low end, the inner paper filtering inside the filter lasts for at least 3,000 miles before cluttering and allowing unfiltered oil to pass through. A premium or long-lifeĀ filter has a cellulose and synthetic filter product that traps almost all of the molecules trapped in your oils and could do so for a great range.
