Fitment note
Listed dimensions: Length: 9.4 in | Outside diameter: 4.1 in | Inside diameter: 0.4 in. Use dimensions as a second check, not as the only buying method.
Filter size note
The listed dimensions point to a mid-size element length at 9.4 in and normal outside diameter at 4.1 in. Use that as a fitment sanity check against the old filter.

The horsepower and filter-size combo says this is not just a catalog lookup. If the tractor works in dust, restriction checks should happen earlier than the generic chart.
Engine airflow note

Clean loose dust from the air cleaner housing before pulling the filter. Never run the tractor with the filter removed, even for a quick test.
Massey Ferguson 1078 Air Filter FAQs
Which Massey Ferguson 1078 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 2127378K1 when you meant the safety filter, or 3703704M91 when you meant the outer filter.
Does the Massey Ferguson 1078 filter size look right for its horsepower?
The useful read is not the raw size by itself. Compared with the 75 hp engine class, the filter size looks reasonable for the power class, but dusty work can still load it quickly. Use that to decide how cautious to be in dusty work.
Why should I compare the old Massey Ferguson 1078 filter before buying?
Do not buy from the title alone. Match 7068311M91 against the removed filter, then check gasket shape, end-cap depth and cover fit before starting the tractor.
Can I match a Massey Ferguson 1078 air filter by size?
A mid-size element can still have different end caps across brands. Use size to narrow the search, then use the part number and seal style to make the decision.
Why does the full Massey Ferguson 1078 air-filter number matter?
The main number 7068311M91 should be treated as the control number. The other numbers need their own fitment checks, not blind substitution.
Should I buy separate outer and primary filters for a Massey Ferguson 1078?
The outer filter is the dirt-catcher; the inner filter is the backup. Service them with different expectations instead of replacing both out of habit.
Why not stretch a dirty Massey Ferguson 1078 air filter under load?
The horsepower and filter-size combo says this is not just a catalog lookup. If the tractor works in dust, restriction checks should happen earlier than the generic chart.
Official information note
Mistakes do happen. Air filter specs can change by year, engine, serial range, market and air cleaner housing. Check the old filter, operator manual, parts book and official masseyferguson.com website before ordering or installing an air filter.
