How to change language

We need to change language from english to italian... how should we proceed? we need to download a component?

You should find the translation for these text in the language file of JA Megafilter component:

root/language/en-GB/en-GB.com_jamegafilter.ini

If this file doesn't exist in IT language folder on your site, pls copy it from EN folder >> and translate as you wish.
