Once again Subaru has failed the enthusiast by placing a corrugated plastic restrictive hose between the turbo and the intake system. But PERRIN has devised an easy to install and attractive solution to this problem. Available in both 3” and standard sizes PERRIN™ offers choices for any turbo upgrade. Constructed of 6-ply silicone for strength, flexibility,  maximize performance, prevent noise,  utilize all available area and ease installation. Competitors try to imitate the benefits found with PERRIN™ but each fails in the attempt. We still maintain the status as the only inlet hose that can be installed without the costly removal of the intake manifold. Why bother with expensive gaskets, dangerous fuel, slippery coolant and additional time spent to install the inferior competition. Our inlet tubes can be installed in as little as 45 minutes! Why spend your entire weekend removing the intake manifold when you could be out enjoying the new performance you have discovered with the PERRIN™ inlet hose. Available in red, black and blue.
