The AGP lower intercooler hard pipe for the 03-06 Evo 8 & 9 is a great upgrade over the restrictive stock intercooler pipe. The AGP Lower Intercooler Hard Pipe is constructed from 2.5 inch aluminum mandrel bent tubing and is completed with a highly polished finish. Included with this product is a 4-ply silicone reducer and high strength hose clamps to adapt to the factory turbo on the Evolution VIII and IX. The hard pipe will also perfectly adapt to the factory intercooler or any other aftermarket intercooler with the inlet/outlet in the factory location.
