After dominating the opening 45 minutes, Belgian forward Laurent Depoitre put Town in front in the first minute of the second-half - expertly brushing aside the attentions of Harry Maguire before clinically finishing past Kasper Schmeichel.
But the joy was short-lived as Jamie Vardy equalised from the penalty spot four minutes later before Kachunga’s effort was denied by the officials.
But who was Huddersfield Town's Man of the Match? Have a look below at Blake Welton’s assessment and have your say with our gadget as well.
Few nervous moments collecting and couldn't do anything about Jamie Vardy’s penalty - 7
By far his best game so far this season and back to his marauding best throughout - 8
Covered Chris Lowe well when his German counterpart found himself in trouble at full-back - 8
Had a great chance to make it 2-1 early in the second-half but his distribution from the back is still a worry - 7
Had a rush of blood to give away Leicester City’s penalty immediately after taking the lead - 7
Pinpoint delivery and passing at every opportunity and was made for the Premier League - 8
A shaky start but grew into the game, needs to be careful with his tackling though - 7
Inventive and showed some good touches before running out of steam in the second-half - 7
Great assist on his Premier League debut and loved getting stuck in for a little fella - 8
Question marks remain over his best position but impressed on the left-hand side - 8
A colossal performance from a monster of a forward and fully deserved his goal - 9 (MOTM)
Collin Quaner (for Elias Kachunga, 74) -Should have done better with an Aaron Mooy cross - 6
Jonathan Hogg (for Abdelhamid Sabiri, 82) - Didn’t have long enough to make an impression - NA
Rajiv van La Parra (for Laurent Depoitre, 90) - Didn’t have long enough to make an impression - NA
