Jay Bothroyd silenced the Coventry boo-boys with a menacing display against his former club as Championship promotion hopefuls Cardiff stretched their unbeaten league run to 10 matches with a 2-0 win at the Ricoh Arena.
Bothroyd, who spent three years with the Sky Blues before leaving to join Italian outfit Perugia on a free transfer in July 2003, had his every touch roundly jeered by the home supporters.
But the former Arsenal youngster had the last laugh when he lashed the ball home from close range after 33 minutes after Keiren Westwood had saved his initial far-post header.
Bothroyd's strike partner Ross McCormack sealed the points for Cardiff with a second goal just after the hour.
McCormack had two chances to extend Cardiff's lead in first-half injury-time but Kieren Westwood got down well to save before the striker mishit the second chance wide from 10 yards.
The Scot made amends after the break though when he latched on to Gavin Rae's pass and slid the ball under Westwood to put the game beyond Coventry with his 16th goal of the season.
