Description

The Wehrli 3.5-inch High Flow Passenger Side Intercooler Pipe replaces the restrictive factory plastic pipe in 2017-2019 GMC Sierra 3500 HD models, improving airflow and engine reliability. Made from 14-gauge aluminum, it features a CNC machined flange with a double o-ring seal and an upgraded silicone boot with stainless steel T-bolt clamps. The Cat Yellow powder coat finish adds durability and aesthetic appeal, and it includes a threaded bung for the OEM Intake Temperature Sensor.
