The fuel injector on a diesel vehicle carefully delivers the proper amount of diesel fuel into the engine for optimal performance. This involves a careful calculation that takes into account quantity, timing, atomization, and other parameters that you don’t want a low-quality fuel injector performing. An inferior part will, at best, lead to reduced performance and, at worst, render your vehicle undrivable.
If your diesel fuel injector has failed, either an OEM or aftermarket replacement may provide the high-quality performance your vehicle needs. Each has its own advantages and disadvantages, however.
OEM Fuel Injectors Provide Reliability at a Premium
An original equipment manufacturer fuel injector, like any OEM part, is identical to whatever fuel injector originally came in your vehicle. The part isn’t only compatible with the vehicle, but it’s comprised of the same components as the original one and assembled by the same company. The part is guaranteed to function just as well and has been through all the same testing as the original one. Your vehicle manufacturer fully stands behind this fuel injector and will support it with their OEM part warranty.
The quality assurance that an OEM injector provides comes with a premium, however. Because these parts are only available from officially approved manufacturers and must be approved by your vehicle manufacturer, they tend to be the most expensive option. In many cases, they cost a lot more than an aftermarket option.
Aftermarket Fuel Injectors Provide Reliability and Affordability
An aftermarket fuel injector may be manufactured by any company that makes a compatible part for your vehicle, and these are often much more affordable as a result. The competition of multiple companies manufacturing the same part causes prices to be reduced.
Quality assurance, however, isn’t always the same with an aftermarket part. Whereas your original vehicle manufacturer dictates what company can make an OEM fuel injector and what specifications that injector must meet, the quality of an aftermarket part is left entirely up to the company that makes it.
The lack of uniform control introduces some obvious issues, for not every aftermarket parts manufacturer has the same standards. Some companies build aftermarket parts that meet all OEM standards (or even exceed standards), but other companies may cut corners and create inferior parts.
Finding an Aftermarket Diesel Fuel Injector from a Quality Manufacturer
The best solution is often to find an aftermarket fuel injector that’s made well, as this affords the best combination of quality and affordability. Thankfully, it’s easy to identify such a part. A high-quality aftermarket fuel injector will:
- Meet or exceed all OEM requirements
- Be built by a known brand in the aftermarket parts sector
- Come with a warranty
There are many aftermarket injectors that meet these criteria and will perform well in your vehicle for a long time. For help finding the right one for your model, contact J&S Diesel. We carry a large array of diesel fuel injectors, and we stand behind each one.
Diesel fuel comes in a couple of different grades, but drivers generally don’t need to worry about which grade they’re using, thanks to government regulations. What’s more important for your vehicle’s fuel injector and engine is the condition of the fuel you use. Grading Based on Type Just as gasoline is rated by how much octane it [...]
As the summer heat sets in, keeping your diesel engine cool is absolutely essential. Overheating can leave you stranded on the side of the road, necessitate emergency repairs and even result in extensive damage to the engine block. Thankfully, keeping your diesel in good working order is simple with routine maintenance. Important Maintenance Tasks to Keep [...]
Diesel engines today feature precise and advanced engineering, but they still run on the basic process of combustion. As air is mixed with fuel, the fuel burns to produce power that’s then translated to the vehicle. In many cases, increasing the air that flows through an engine will result in better combustion and more power. [...]
