It seems that Purolator is recommending the ML16817 filter for the ST1300 and motorcycles in general. I switched from oem to PL14612. From Google I found the comparison below. Anyone use the ML16817 or thinks that the PL14612 is not suited for a motorcycle.
The Purolator PL14612 (PurolatorONE) and ML16817 (Purolator Motorcycle) are different filter types. The PL14612 is a passenger car/light truck filter for high-mileage engine protection, while the ML16817 is specifically designed for powersports applications (motorcycles/ATVs). They are generally not interchangeable due to different thread sizes and specifications.
Key Differences:
Purolator PL14612 (PurolatorONE): Designed for automotive applications, offering advanced engine protection and high-efficiency filtration for cars.
Purolator ML16817 (Motorcycle): Engineered for the high-pressure, high-RPM requirements of motorcycles, often featuring a heavy-duty casing and specific bypass valves.
Recommendations:
Always use the filter listed for your specific vehicle. Even if they appear similar, Purolator filters are built for specific vehicle specifications.
The PL14612 is for passenger cars (e.g., Nissan, Mazda), whereas the ML16817 fits select motorcycle/ATV applications.
