The original factory hose that connected to the airbox wouldn't reach the snorkel intake. Remember: The kit is designed for Australian vehicles. We searched around California Mini-Truck's parts yard and found an intake hose off a '92 2.3L Mazda pickup, which fit perfectly between the snorkel and factory airbox hose. You can also use flex hose found at hardware and automotive parts stores. The factory airbox hose is on the left, with the Mazda intake hose in the center, and the snorkel hose on the right.
