Improve throttle response and acceleration with this HPS Performance Cold Side Upper Intercooler Pipe Kit. Air flow is optimized to generate an additional 8.9 horsepower and 8.5 lb-ft. of torque without re-tuning the ECU. This kit replaces the stock plastic upper cold side charge pipe and rubber boots with a 2.5" custom mandrel-bent 16-gauge 6061 aluminum tube, our signature HPS 4-ply reinforced silicone hoses, and 100% stainless steel embossed clamps. We utilize this design to increase the air volume and allow for easier installation. Reduce the risk of boost leaks and get the most out of your turbocharged vehicle.
