Vishnu Prasad extended his championship lead after an opportunistic win in the first race of the JK Tyre Racing after Karthik Tharani was penalised from race lead.
The National championship winner Tharani was on-song battling with Prasad and polesitter Costantino Peroni throughout the 10-lap race.
A bittersweet moment for Tharani who was given a two-position penalty for overtaking under the yellow flag which demoted him to third.
That gave Prasad another win with Peroni settling for second. Prasad also clocked the fastest lap of the race with a time of 2m08.466s at the Buddh International circuit.
Akhil Rabindra finished a handy fourth pushing Nayan Chatterjee to fifth and Krishnaraaj Mahadik was sixth, right at the tail of Mahadik, making up five places in the process.
Guest Indian driver Parth Ghorpade finished a distant seventh, making up two places, ahead of Chittesh Mandody at eighth.
The top 10 was completed by Ananth Shanmugam at ninth and Akash Gowda 10th, losing four places after starting sixth.
