Johnson backed up his nine-wicket haul in the opening Brisbane Test victory with another eight scalps in Adelaide to have 17 wickets for the series at the stunning average of 12.50.
The fearsome left-hander, reaching speeds of up to 150 kilometres (93 miles) per hour, has had the Englishmen ducking for cover.
He was not selected for Australia's 3-0 losing series in England this year, but is now the most substantial difference between the two sides.
Johnson was cleared to play in the next Test in Perth despite a mid-pitch collision with batsman Ben Stokes during the 84th over of England's second innings on Sunday.
International Cricket Council match referee Jeff Crowe said both players pleaded not guilty to making inappropriate and deliberate physical contact. Reports said the charges were subsequently dismissed but there was no immediate confirmation.
Australian skipper Michael Clarke says the trick has been finding what methods work to bring out the best in Johnson, who once bowled erratically and was the target of England's taunting Barmy Army supporters.
Johnson has now found success under the tutelage of skipper Clarke, team coach Darren Lehmann and bowling coach Craig McDermott.
