Massey Ferguson 398 Air Filter FAQs
Which Massey Ferguson 398 air-filter parts should be changed together?
For a full parts check, separate the service element from the safety element: buy the outer/primary service element first, then buy the inner safety element only if it is dirty, damaged or due. Do not accidentally order 7068069M1 when you meant the safety filter, or 3703704M91 when you meant the outer filter.
Why should I compare the old Massey Ferguson 398 filter before buying?
Because this listing shows a primary, outer and inner safety element setup, the risk is ordering one correct number and one wrong companion element. Keep 7068311M91 as the main reference, then confirm the other elements separately.
Does engine power change how I service the Massey Ferguson 398 air filter?
At this power level, a dirty filter can show up as weaker pull, smoke or higher heat under load. Use job conditions and the restriction indicator ahead of a fixed schedule.
What does the outer-filter listing mean for the Massey Ferguson 398?
This looks like a multi-element setup. Keep the outer/primary service element and the inner safety element separate when ordering, because mixing up 7068069M1 and 3703704M91 is the easy mistake.
Why does the full Massey Ferguson 398 air-filter number matter?
Multiple numbers are useful only if each one is tied to the correct element position. Wrong element in the right brand is still wrong.

One alternate number is useful, not magic. Confirm it physically before trusting the compatibility claim.
Does the Massey Ferguson 398 engine setup affect air filter fitment?
Use the engine info to sanity-check parts listings. If the listing points to a different engine family, slow down and verify before ordering.
