A first intake pipe has one end connected to a second side of the surge tank which faces a second cylinder bank, and a second intake pipe has one end connected to a first side of the surge tank which faces a first cylinder bank. Adjacent the intake pipe ends, the first and second intake pipes are inversely bent near the second and first cylinder banks respectively, and have middle portions crossing below the surge tank and have other ends connected to the first and second cylinder banks. The first and second intake pipes are arranged in an alternating position in the cylinder-row direction. First and second branch pipes have upper ends connected into the surge tank and lower ends connected to adjacent other ends of the first and second intake pipes. Variable intake elements are disposed at the upper ends of the branch pipes to open and close.
