FILTER KITS

Filter Kits For Peterbilt Trucks

Filter kits bundle the essential filters needed for a complete PM service into a single purchase — engine oil filter, fuel filter(s), coolant filter, and air filter packaged together for a specific engine application. Buying filters as a kit simplifies procurement, ensures all filters are serviced at the same interval, and typically saves money versus buying each filter individually. We carry filter kits for Peterbilt trucks running PACCAR MX, Cummins ISX/X15, and other common diesel powerplants.

Frequently asked questions about filter kits

What filters are typically included in a Peterbilt PM filter kit?

A standard PM kit for a Class 8 Peterbilt typically includes a lube filter, primary and secondary fuel filters, a coolant filter, and sometimes an air filter depending on the kit's scope. Engine-specific kits for the PACCAR MX-13 may also include a crankcase ventilation filter element. Always verify what's included in a kit against your specific PM checklist to confirm you have everything needed before starting the service.

How often should I do a full filter service on a Peterbilt truck?

Standard PM intervals for most Class 8 diesel applications are every 25,000 miles under normal highway conditions, though some fleets running low-sulfur fuel and premium synthetic oil have extended to 50,000-mile oil change intervals with oil analysis programs to confirm. Air filters are inspected at every PM but typically replaced based on restriction indicator reading rather than mileage alone. Always follow your engine manufacturer's maintenance schedule as the authoritative reference.

Are aftermarket filter kits as good as OEM for a Peterbilt engine?

Quality varies by brand. Reputable aftermarket filter manufacturers like Fleetguard, Baldwin, Wix, and Donaldson produce filters that meet or exceed OEM filtration and flow specifications for PACCAR and Cummins engines. Using a low-quality filter to save a few dollars at PM can cost far more in engine damage — filtration efficiency, bypass valve settings, and media construction matter, particularly for the fuel filter on modern high-pressure common rail injection systems.
