About FitLookup

FitLookup answers one question: which filter fits my car?

Pick your year, make and model and you get the oil, cabin air and engine air filter part numbers for your engine. Each number links to the carmaker's or filter maker's catalog page it came from, with the date we checked it. Today that covers 50 models sold in the US.

Who runs it

FitLookup is independent. It isn't owned by a carmaker, a filter brand or a store, and no one pays to be listed. The lookups are done by AI software and checked again by a second, separate pass. How we check explains each step.

How it pays for itself

The Amazon buttons are affiliate links. If you buy through one, we earn a small commission at no extra cost to you. It never changes which part we say fits.
