Filter size note The listed dimensions point to a mid-size element length at 12 in and large outside diameter at 10 in. Use that as a fitment sanity check against the old filter.
Power range note 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.

Massey Ferguson 4255 Air Filter FAQs

Why compare Massey Ferguson 4255 horsepower with filter dimensions?

Comparing power and element size helps catch bad cross-references. A tiny replacement for a harder-working engine should make you suspicious before installing it.

Why should I compare the old Massey Ferguson 4255 filter before buying?

If the old filter is missing, use 6259119M91 plus the housing measurements as a two-step check. If either the seal or cover depth is wrong, do not run it.

What should I buy for a full Massey Ferguson 4255 air-filter service?

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.

Which Massey Ferguson 4255 air-filter measurement matters most?

The dimensions are useful only as a fitment screen. The final test is whether the element seats square, the cover closes normally and the seal lands where the old one did.

What is the biggest fitment trap with the Massey Ferguson 4255 air filter?

The trap is assuming a wide element is close enough because it looks right online. The seal face, end-cap depth and cover pressure have to match, otherwise dust can bypass the media.

Why does the full Massey Ferguson 4255 air-filter number matter?

The primary number format is a Massey-style M-suffix number, while the page also has separate companion numbers. That is exactly where copy-paste ordering mistakes happen.

Can the Massey Ferguson 4255 lose power from a dirty air 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.

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.
