The Bees buzzed back to winning ways with this emphatic performance.
After the disappointing performance at Birmingham where the Bees failed to get out of second gear the Bees bounced back in style.
From the kick off it was evident that the pace of the game was going to be much faster than at St Andrews.
Brentford are at their most dangerous when they move the ball fluidly and at pace and it was such a move which resulted in Long putting the Bees in the lead after four minutes with a powerful drive after four minutes.
The Bees spurned to great chances to double their lead before Bunn equalised for Huddersfield midway through the first half.
Long got his second with a tap in after 51 minutes and from them on in it was virtually all one way traffic.
Pritchard got the Bees third after 70 minutes and Toral added a deserved fourth in extra time.
The win moved the Bess back into the play off places, but Ipswich have a game in hand playing tomorrow night
