Brentford made it two home wins out of two in the Dean Smith era as they brushed Huddersfield aside with a dominant first-half performance.
Goals from Sergi Canos, Lasse Vibe and Alan Judge gave the Bees a comfortable lead at half-time on an unseasonably warm December afternoon.
The Terriers, though, pulled one back within moments of the restart as Joe Lolley fired home from eight yards.
However, Ben Chilwell brought down Judge in the penalty area and the Irishman scored his second from the spot before Kyle Dempsey's late consolation.
Brentford made the better start and a wonderful ball from Judge sent Vibe clear down the left. The Dane cut inside to find John Swift. The Chelsea loanee set up Liverpool counterpart Canos. The Spaniard turned his man to slot home to give the home side a 1-0 lead after five minutes.
Lasse Vibe made it 2-0 after 21 minutes when he beat the offside trap to run onto James Tarkowski's long clearance and rifled the ball past Jed Steer and into the roof of the net.
The Bees wrapped up the points when Judge squeezed the ball home from a free-kick by the touchline after a Tommy Smith handball.
Huddersfield manager David Wagner read his players the riot act at half-time and replaced Duane Holmes and Ishmael Miller, who had spent most of the first-half on the floor, with Nakhi Wells and Kyle Dempsey.
Wells was into the action within 30 seconds and he set up Lolley to make it 3-1 30 seconds after the restart.
However, Ben Chilwell shoved Judge over in the box eight minutes later and the Irishman lashed the ball home to make it 4-1.
Maxime Colin had a chance to make it five after creating the chance virtually by himself but curled over the bar.
Huddersfield had a second goal in stoppage time after Toumani Diagouraga slipped to allow Dempsey to score after David Button saved Jamie Paterson's first effort.
