DOC and DPF are crucial parts of the emission control system in a diesel engine. DOC and DPF are designed to remove particulate matter (PM) and other contaminants from the exhaust gas stream. This ensures that the engine meets emission standards, runs more efficiently, and produces less pollution. 

Over time, however, the DOC and DPF can become clogged with PM and other contaminants, which can lead to decreased performance and increased pollution. To keep your engine running at peak performance and meet emission standards, you need to replace your DOC and DPF regularly. 

That being said, replacement parts are available from aftermarket suppliers at a fraction of the cost of genuine parts from the engine manufacturer. In addition, aftermarket DOC and DPF filters are often of equal or better quality than genuine parts.

Not convinced? Below, we explain the benefits of using aftermarket DOC and DPF replacement parts in more detail.

Aftermarket DOC and DPF Replacement Parts Are Cheaper

The biggest advantage of using aftermarket DOC and DPF replacement parts is that they are significantly cheaper than genuine parts from the engine manufacturer. In some cases, aftermarket parts can cost up to 50% less than genuine parts. 

This is because aftermarket suppliers don’t have the same high overhead costs as the engine manufacturer. They also benefit from economies of scale – they produce a large volume of parts so that they can sell them at a lower price.

As a result, they can sell their parts at a lower price point, which saves you money. In addition, aftermarket suppliers often offer discounts and promotions, which can further reduce the cost of replacement parts. 

Aftermarket DOC and DPF Replacement Parts Are Often of Equal or Better Quality

Another advantage of using aftermarket parts is that they are often of equal or better quality than genuine ones. Aftermarket suppliers use the same or similar materials and manufacturing processes as the engine manufacturer. In some cases, aftermarket parts are actually better than genuine parts because they’ve been designed to address specific problems that have been identified in the field. 

For example, if the original design of a DOC or DPF filter is prone to clogging, an aftermarket supplier may redesign the filter to prevent this from happening. As a result, aftermarket parts can actually improve the performance of your engine. 

It’s important to note that not all aftermarket suppliers are created equal. Some suppliers cut corners to produce parts cheaply, which can lead to lower quality. It’s important to do your research and buy from a reputable supplier.

Aftermarket Offers a Wide Selection of Perfectly Fitted Parts

When you need to replace your DOC and DPF, you want to be sure to find parts that perfectly fit your engine. Otherwise, you risk decreased performance and increased pollution. 

The good news is that aftermarket suppliers offer a wide selection of perfectly fitted parts for all makes and models of diesel engines. This means you can find the exact details you need to keep your engine running at peak performance.

Aftermarket Suppliers Offer Warranty and Support

When you buy aftermarket DOC and DPF replacement parts, you also benefit from the support of the supplier. Most reputable aftermarket suppliers offer a warranty on their parts. This means that if a part fails prematurely, you can get a replacement at no cost. 

In addition, aftermarket suppliers usually have a team of experts who can help you with installation, troubleshooting, and other issues. This support is crucial in ensuring that your engine runs smoothly and meets emission standards.

Conclusion

There are many benefits to using aftermarket DOC and DPF replacement parts. They’re cheaper than genuine parts and often of equal or better quality. As such, they’re a great way to keep your engine running at peak performance without breaking the bank.

When buying aftermarket parts, however, it’s important to buy from a reputable supplier. Unfortunately, it’s easy to find inferior aftermarket parts if you’re not careful and don’t know what to look for.
