One of the most crooked cops in NYPD history has created a cigar line with a drug dealer he was in cahoots with — and has named it after the Brooklyn precinct he disgraced.

Former Officer Michael Dowd, 55, spent 12 years behind bars for shaking down cocaine dealers, swiping their drugs and reselling them while working in Brooklyn’s 75th Precinct in the late ’80s and early ’90s.

Now he’s teaming with a former drug cohort, gang leader Adam Diaz, to sell cigars from the Dominican Republic under the brand name The Seven Five — after Dowd’s old precinct.

Diaz lives in the Dominican Republic after a prison stint in United States.

The cigars’ bands feature the men’s names along with a photo of Diaz and a silhouette of Dowd in uniform.

Printed on their wooden boxes are the phrases, “Nobody can touch me. Nobody can touch my crew,” and “The King of Brooklyn.”

“It’s a disgrace that he’s in business with a drug dealer,” said Joe Hall, a former 75th Precinct detective now with the Special Narcotics Prosecutor.

“But that’s probably the only friend that he has. Drug dealers will probably be the ones who buy these cigars.”

The cigars are produced by the Dominican company Tabacalera Palma and available at the LI Tobacco Outlet in Ronkonkoma, LI — but not for long.

The store’s owner, Fred Udle, 51, said he bought 75 boxes to stir up publicity, but in light of the controversy, has decided not to reorder once they sell out.

“I’m close friends with a lot of my customers, and they are like family, and it upset them,” he explained.

“I thought it would be great publicity for my shop, but I understand why the cops don’t like him.”

Udle said the Patrolmen’s Benevolent Association called him, saying cops would boycott the store.

So far, he has sold around 30 boxes, he said.

A law enforcement source who had worked with Dowd was stunned that the ex-cop would use the name of his old precinct, and said Diaz’s involvement “makes it even more of a slap in the face.”

“If he had any sense of decency, he’d give all the proceeds to the Widows’ and Children’s Fund,” he said.

Dowd’s crimes are the subject of a documentary also called “The Seven Five,” airing on Showtime.

Dowd’s son said his dad would not be commenting.
