How to change this, to put a range of data from item?
Like year of the car?
thank you

Its not supported by custom fields.

so i need to code it ?

Yes, it may not be so complicated for specific usage

can u explain me how? or where i can find some guides?

There are no guides for development. Developer should know what to do.
You create 2 select boxes with min and max.
Then you can use hook search_conditions to create new swl co ditions.
I.e. themes use this hook to add extra fields to search so you might get inspired here
