A humbling 7-0 defeat in Gothenburg last time out sent Lulea back up north with their tails between their legs and with something of a point to prove back on home ice. In defence, they stepped up, but failed to capitalise in attack in a match that was still goalless after 40 minutes.
Frolunda's first powerplay chance late in the first period after holding by Heikki Liedes was ended 10 seconds in when Ivar Stenberg was called for tripping. The visitors then managed to hold out a man down late in the second period after Dominik Egli was called for another trip.
The away side were 19-10 up on shots on goal after two periods, so perhaps it was no surprise it was they who finally broke the deadlock with less than four minutes to play when Noah Dower Nilsson scored for the second time in the series.
But after waiting over 56 minutes for one goal, a second arrived 39 seconds later - Lulea attacked down the left before Brian O'Neill squared to Isac Hedqvist, whose strike trickled past the goaltender and in to send the match to overtime.
It took almost nine minutes for either side to give an inch, but it was Frolunda who blinked first as Nicklas Lasu was called for hooking, and with only 20 seconds of the powerplay left, Mathias Brome swept home the winning goal.
2-1 to Lulea both on the night and now in the series, and the teams stay at the Coop Norrbotten Arena for game four on 29th March.
In the other game, Skelleftea moved to one win away from a place in the last four, beating Malmo 4-2 on the road to take a 3-0 series lead with the chance to complete a sweep in game four at Malmo Arena on 29th March.
As in both previous games in the series, and their most recent regular season game, the Redhawks took the lead. Midway through the opening period, Elia Pedrotti found Linus Oberg, who slotted his second goal in as many games.
But, also as in the three previous head-to-heads, Skelleftea came from behind to win - 13 minutes into the second period, Viktor Grahn and Oscar Lindberg combined for Mikkel Aagaard to equalise with his second of the quarter-finals.
Then came a real blow to the home side, as the visitors completed the turnaround in the final minute of the period through Jonathan Pudas.
Pontus Johansson looked to have put the game to bed when his goal went all the way through with a little over three minutes to go, but a powerplay chance brought Malmo right back into it a minute later, through Fredrik Handemark.
Malmo gambled by taking off the goaltender to try and force a late leveller, but it backfired with still over a minute to go, and Rickard Hugg's empty-net goal finally sealed another victory for Skelleftea.
