- Customer must contact PHR prior to ordering this. Customer must supply the turbo manifold, turbo, and/or intercooler to PHR for fitment on our mock up chassis unless it is deemed unnecessary. This price is for the basic coupler to turbo and coupler to intercooler style intercooler piping. If needing a different clamping syle, the cost of the pipe will not change, but customer will need to purchase the additional flange and clamp assemblies.
