HPS Polish Intercooler Pipe Complete Kit (Hot and Cold Side) with blue high temp 4-ply reinforced silicone hoses is a direct replacement for 2015-2020 Mustang Eco boost 2.3L Turbo oem intercooler pipings and rubber hoses. Made from lightweight mandrel bent aluminum tubing (2.5" OD for the HOT side, 2.75" OD for the Cold Side), the charge pipe kit has less bend and better air flow compared to the oem restrictive design. The bead rolled pipe ends prevent couplers from popping off under boost. The included HPS high temp 4-ply reinforced black silicone hoses with 100% stainless steel t-bolt clamps can withstand minimum 50+ psi of boost and replace the factory rubber couplers, which often crack or fail over a period of time. The intercooler piping kit optimize and smooth out the air flow, increase horsepower +17.1 Whp , torque +16.9 Ft/lbs. and improve throttle response without re-tuning the ECU. Fits 2015-2020 Ford Mustang Ecoboost 2.3L Turbo. Compatible with oem and aftermarket intercoolers utilizing the factory oem piping.
