Chris Weidman, James Te Huna, Joey Beltran and Alex Caceres were the bonus winners.
Each earned a cheque for $40,000 thanks to their standout efforts.
Chris Weidman earned Knockout of the Night for his second-round TKO of Mark Munoz in the main event.
James Te Huna and Joey Beltran earned Fight of the Night for their all-out war over three round.
Alex Caceres earned Submission of the Night for his triangle choke of Damacio Page in the second round of their fight, after several close calls in the first.
The bonus awards were announced at the post-fight press conference by Dana White, who also gave the attendance as 4,250 and the live gate as $163,495.
UFC on FUEL TV 4 took place at the HP Pavilion in San Jose, California - former home of Strikeforce - and commenced at 14:30, which combined with the mid-week slot to make for a low attendance by UFC standards.
