OEM Diesel Particulate Filter - DPF

When aftermarket isn't an option, and your fleet requires factory-original hardware, our collection of OEM Diesel Particulate Filters (DPFs) provides the reliable solution you need. We specialize in sourcing genuine surplus OEM filters for Cummins engines, ensuring you get the exact flow rates and substrate quality your truck came with from the factory.

If you're chasing high backpressure codes or your engine won't finish a stationary regen, swapping in a genuine part like the Cummins 4394227 or 2871463 is often the fastest way to get your emissions system back to 100% efficiency and clear those persistent fault codes.

At DPF Super Store, we focus on making OEM quality accessible to Canadian owner-operators and repair shops. Unlike local dealerships that may have long backorders, we maintain an in-stock inventory of popular Cummins modules in our Vancouver and Toronto warehouses. This means you get fast, domestic shipping across Canada without the wait or the cross-border customs fees.

Every OEM filter we sell is a genuine factory unit, giving you peace of mind that your fitment will be perfect and your sensors will read exactly as intended. If you need help verifying your part number, just reach out—we’re here to help.
