"Besoin" must be followed by "de"; the correct construction is "besoin de plus d'infos".

Cultural Tip
The word "infos" is informal; in formal letters or official documents you should use "informations". Also, "à ce sujet" is a neutral, safe choice, while "à propos" or "sur ce sujet" can sound slightly more casual. French speakers often prefer the concise "plus d'infos" in spoken language, but be careful not to drop the apostrophe after "d'".
