Join the hoses and metal pipes to the turbo's compressed air outlet, and then attach these pipes and hoses to one side of the intercooler. Remove any filters or tubes from the engine's air intake. On the other side of the any hoses and pipes, and then connect these to the engine's air intake system. 7. Check to make sure all the fittings, bolts, and taps are secure. 8.
