Guenther jumped to the top of the order late on with a time of 1m08.946s, knocking Stoffel Vandoorne off the top spot.
Team-mate Edoardo Mortara then improved to go just 0.191s slower than Guenther and make it a 1-2 for the Monaco based team.
It was a trouble free practice session in Indonesia, with lap times tumbling throughout the session. Jean-Eric Vergne topped the order early on with a time of 1m12.011s, which wouldn’t stay quickest for long.
Pascal Wehrlein, Vandoorne, Mortara and Guenther swapped fastest times and would all finish inside the top five at the chequered flag.
Mitch Evans squeezed into fourth, ahead of Wehrlein and Jake Dennis.
Sam Bird took seventh, just ahead of Antonio Felix Da Costa and Vergne, who slipped backwards late in the session.
Sebastien Buemi took 10th, comfortably ahead of championship leading team-mate Nick Cassidy. Cassidy could only manage 17th quickest, ahead of only championship new-comer David Beckman – who replaces Andre Lotterer for the Jakarta weekend – Norman Nato, Lucas Di Grassi, Roberto Merhi – replacing Oliver Rowland – and Robin Frijns.
