Matheus Cunha inspired Wolves to blow away Leicester as the in-form hosts recorded a sixth consecutive Premier League victory.
The striker scored one and made goals for Jorgen Strand Larsen and Rodrigo Gomes as Wolves made it six straight top-flight wins for the first time since 1970.
Wolves goalkeeper Jose Sa saved Jamie Vardy’s second-half penalty as the Foxes’ goal woes continued.
It means the striker remains on 198 goals for the club with four games of his Leicester career left.
Cunha, who has a £62.5m release clause and is expected to leave Molineux this summer with Manchester United interested, scored his 15th Premier League goal of the season.
Wolves’ biggest concern – having ensured survival earlier this month – will be how to replace the Brazil international who has been key to ensuring they maintained their top-flight status.
For the immediate future, though, they can relax after a routine win over the Foxes, whose season continues to spiral with relegation confirmed last weekend.
Leicester boss Ruud van Nistelrooy cut an isolated figure on the touchline, compared to Wolves head coach Vitor Pereira who was serenaded by home fans inside Molineux after steering the hosts to safety and 13th in the table.
His first game in December was a 3-0 win over the Foxes at King Power Stadium which still left Leicester out of the bottom three and two points ahead of Wolves – they are now 23 behind.
That their fates had been settled meant, with nothing riding on the game, Molineux rarely came to life until Cunha steered in Rayan Ait-Nouri’s low cross midway through the first half.
Ait-Nouri had already gone close, while Leicester had offered nothing, the start of Vardy’s farewell tour amounting to little more than a footnote – even with his penalty miss after he went over following Sa’s challenge.
By then Strand Larsen had already added a second 10 minutes after the break when he fired in low, minutes after ballooning the ball over from two yards.
Gomes added a third from another Cunha pass with five minutes left to cap victory.
Pereira’s impact evident as Wolves march on
As Wolves celebrated with supporters, the team holding hands to salute the Sir Jack Hayward Stand, the unity at Molineux was clear.
Pereira was serenaded by home fans with his now-famous phrase “First the points, then the pints” and the head coach will be expected in the Wolverhampton Wetherspoons this evening.
He has made a point of going into the town to celebrate wins with fans – to get to know the area and understand the club’s supporters – and it is unlikely he will need to buy a beer given the impact he has made since his arrival in December.
Wolves are now above Everton, Manchester United, Tottenham and West Ham in the table.
Pereira took charge when Wolves were second bottom – and behind Leicester – and engineered a turnaround of impressive proportions. He has delivered 10 league wins and 32 points from 18 games.
There will be issues to deal with in the summer – Cunha’s future being the biggest – but Wolves are enjoying the ride for now.
Vardy’s Foxes fairytale ending as a nightmare
If Vardy’s Leicester career has largely been a fairytale, this season has been a nightmare. The striker, who will leave the Foxes when his contract expires in the summer, has described the campaign as a “total embarrassment”.
This was a 17th defeat in 19 league games and an 18th in Van Nistelrooy’s 23 matches in charge. It has been a sorry season, and this was another miserable game, a third 3-0 defeat in their last six outings.
Vardy tried to roll back the years when he won a spot-kick, making sure he was caught by goalkeeper Sa, but his tame penalty summed up Leicester’s day and another powderpuff performance.
Leicester have scored just six goals in the league since 8 December so the travelling fans were denied a chance to celebrate a collector’s item.
Vardy is tantalisingly close to reaching 200 goals for Leicester in his 13 years at the club.
Whether he gets there or not, he will be signing off with the Foxes on their way down and showing few signs they might quickly recover from this jolt of a season.
