The surging Flames look for their eighth win in nine games when they head to Staples Center on Saturday to meet the Los Angeles Kings.
After seeing its season-high six-game winning streak end with a 2-1 road loss to the Edmonton Oilers on Tuesday, Calgary (10-8-2) returned home and responded by beating the Chicago Blackhawks 4-1 on Wednesday.
Iginla scored twice off assists from Tanguay.
"We knew we were going to click at some point and now it's starting to come," said Tanguay, acquired in a trade from the Colorado Avalanche in June for defenseman Jordan Leopold.
Iginla has scored at least 30 goals in each of the last five seasons for Calgary, and now appears headed toward extending that streak. The right wing has 11 goals and 12 assists this season, including five goals and seven assists in his last nine games.
He's scored 21 goals - seven coming on the power play - in 36 career games versus Los Angeles.
Tanguay has 10 assists in his last six games, after recording only five in his first 14.
"If you give Iggy the puck in the slot like that, he's not going to miss too many times," said Tanguay, who had a three-assist game against the Kings last season while playing for Colorado.
Kiprusoff, the reigning Vezina Trophy winner, finished with 25 saves and needs one win to move past Phil Myre into sole possession of fourth place on the franchise's all-time list.
Kiprusoff and Myre, who played for the Atlanta Flames from 1972-78, each have 76 wins.
Since giving up three goals in a loss to the Detroit Red Wings on Nov. 1, Kiprusoff is 7-1 with a 1.13 goals-against average and two shutouts.
Calgary, with 22 points, is tied with Colorado for fourth place in the Northwest Division, but both teams are just five points behind division co-leaders Minnesota and Edmonton.
Los Angeles (7-13-4) suffered a 5-3 defeat to the Dallas Stars on Friday, its seventh loss in eight road games.
Dustin Brown scored twice and Alexander Frolov also had a goal - all on the power play - but goaltender Mathieu Garon gave up four man-advantage tallies, including three to Stars defensemen Philippe Boucher.
"Power plays were the difference in the game," Kings coach Marc Crawford said. "I was not surprised with (Dallas') power play. Their offense comes from their point men and tonight Boucher found holes on three of his shots."
Frolov, meanwhile, has scored seven of his team-high 13 goals in his last five games. The Russian-born right wing was limited to two assists in four games last season against Calgary.
The Kings have a chance to post back-to-back wins for the first time since beating the St. Louis Blues and New York Islanders in the first two game of the season.
Los Angeles defeated the Phoenix Coyotes 5-3 on Nov. 18 in its last appearance on home ice. The Kings' five home wins, though, are the fewest in the Pacific Division.
These teams split four games last season, with the Kings winning the season-series finale 2-1 in a shootout on April 15.
