The Owls produced one of their best performances of the season against Huddersfield on Saturday, winning 2-0 in West Yorkshire.
Miguel Llera and Nile Ranger struck for Wednesday after the break to post three crucial points - making it three wins on the bounce away from home.
It was an outstanding Owls display from front to back and a fully merited victory over promotion rivals Huddersfield.
Wednesday made one change from the 2-0 win over Preston last weekend as Danny Batth returned to side in place of suspended captain Rob Jones.
And the Owls made a promising start to the game, having hit the woodwork inside the first two minutes.
Gary Madine met Michail Antonio's long throw with a looping head that Alex Smithies tipped onto the crossbar with Town able to clear their lines.
Wednesday were seeing plenty of the ball in the early exchanges as the lively Jermaine Johnson struck over Smithies' goal on 12 minutes.
As the half progressed it became an even contest with both sides enjoying pockets of possession albeit without carving out any clear cut chances.
Llera then went within inches of breaking the deadlock with a set piece from 25 yards which drifted just wide before Huddersfield hit back with a chance of their own.
Jordan Rhodes linked up smartly with Danny Ward who raced into the area and unleashed a fierce drive which whistled past the post.
Ward then went close with a free kick that flew just over the bar before the referee brought an end to the first period.
There was a quick tempo about the game after the break and early goal to celebrate for the visitors.
Llera stepped up from 25 yards and - after coming close in the first half - found the back of the net this time with a superb strike over the wall and inside Smithies' left hand post.
The game then exploded into life as Wednesday nearly doubled their advantage.
Antonio struck low and hard but Smithies saved well, as the rebound fell to Nile Ranger but the Terriers keeper was up quickly to make a key save.
Wednesday once again struck the crossbar.
A fine ball over the top from Lines picked out Ranger whose side-footer came crashing back off the upright, with Antonio smashing the rebound wide.
Given the nature of the game, another goal seemed likely and it duly arrived from Ranger.
Jermaine Johnson picked up possession and fed the on-loan Newcastle man through with a fine ball and Ranger shrugged off his marker before slotting home into the bottom corner.
Rhodes couldn't quite connect with Sean Morrison's ball into the box at the far post as Huddersfield searched for a way back into the game.
But Wednesday were resilient and saw the remaining moments of the game out to keep up the pressure at the top of the table.
