The Nerazzurri had the strike pairing and keeper Samir Handanovic to thank for the result, as Andrea Stramaccioni's side continued their rich vein of form away from San Siro
Diego Milito gave the visitors a lead inside 15 minutes while Antonio Cassano ensured the three points would be heading to San Siro outfit in the later stages of the game.
Talk leading up to the match centred around how Inter would pick themselves up from a comprehensive 3-1 defeat to Roma at San Siro two weeks ago, with the trip to the newly-promoted Torino seen as the perfect opportunity to get their Scudetto charge back on track.
Making three changes to the side that capitulated against Zdenek Zeman's outfit, Inter took their time to get into the game, ceding territory and possession to their hosts, who dominated early proceeding without overtly threatening Samir Handanovic's area.
With the match beggining in dour, stolid manner, it took a thunderbolt of an opener from Diego Milito to restore lustre to the match, popping up to hand Inter the advantage in the 14th minute.
On the Nerazzurri's first actual foray forward, a loose ball was seized upon by the Argentine hitman. Taking just the deftest of touches, the 33-year-old let fly from 25 yards, leaving Jean-Francois Gillet grasping at thin air as the ball slammed into the bottom right corner.
Torino responded immediately through Alessandro Sgrigna and Angelo Ogbonna in succession, the striker immediately heading wide as play restarted before the Italy international drew a fine save from former Udinese custodian Handanovic.
Giampiero Ventura's men picked up two bookings in as many minutes, and from the resulting free-kick awarded in the 25th minute, Wesley Sneijder almost doubled his team's lead; the Dutch playmaker powered in an effort that had Gillet diving at full strech to parry away.
Yuto Nagatamo made a hash of things with an attempted backpass to his keeper under pressure, while a searching ball into the Granata's box from Fredy Guarin evaded everyone in brown to find Milito in the 40th minute, who's snap-shot was gathered well by Gillet. The first-half ended with the same scoreline, with chances proving few-and-far-between.
Sgrigna lit up the opening minutes of the second period with a strong run at the heart of his opponents' defence that culminated with a shot hitting the woodwork, but the linesman had raised his flag for offside moments earlier. Sneijder responded for Inter with a speculative effort from distance that flew high over the crossbar in the 52nd minute.
Summer signing Alessio Cerci came off the bench as a statement of intent, with Torino pushing hard against the visitors for the equaliser. Captain Rolando Bianchi next spun to turn Andrea Ranocchia and let loose a shot, although Handanovic proved equal to the task.
Bianchi was then presented a golden opportunity, after substitute Riccardo Meggiorini played in a beautiful ball to his feet, but Inter's keeper was to once more prove his nemesis. Torino continued to be denied reward for their constant endeavour, when Meggiorini broke the offside trap in the 65th minute only to fire into the side netting.
Tension was beginning to rise at the Olimpico, as Guarin became just the latest player to pick up a yellow card from the referee; Alessandro Gazzi failed to capitalise from the ensuing set-piece despite getting a good connection however, jumping to head wide of the post.
The 29-year-old was left ruing what might have been, for Inter ruthlessly sealed the result shortly after. A routine cross from the left in the 84th minute appeared to find Esteban Cambiasso, only for the midfielder to dummy beautifully and allow the ball to reach Antonio Cassano, who made no mistake from five yards.
Inter rounded off their clinical display by shoring up in defence and midfield, with the Milanese giants keeping pace with front-runners and Italian champions Juventus with the result. They welcome Siena to San Siro next week, while Torino remain on three points.
