Officers stopped 27-year-old Gleni Goleci as he was driving on Tuesday and discovered the haul in his boot.
A later search of his flat uncovered six kilos of cocaine and approximately £150,000 in cash.
Goleci, an Albanian national, has been remanded into custody before his next appearance at Isleworth Crown Court next month.
Andrew Tickner, NCA Operations Manager from the Organised Crime Partnership, said: “These seizures mean that it will now be impossible for the organised crime group behind this trade to reinvest their profits into further criminality and exploitation.
“The NCA and Metropolitan Police continue to work in partnership to detect and apprehend individuals suspected of involvement in drug trafficking that is impacting London communities.”
