AEM Charge Pipes are a free-flowing, mandrel-bent aluminum tube charge pipe kit designed to replace the restrictive factory intercooler piping on specific turbo charged BMW models and offer a wide range of performance customization options. AEM charge pipes have been engineered to reduce turbo charged air pressure loss as well as dramatically increase air flow from the turbo through the intercooler. The charge pipes are constructed from lightweight aluminum with a durable gunmetal gray powder coated finish. For additional horsepower gains and improved engine compartment aesthetics, AEM offers a wide range of Cold Air Intake System that can be installed into your vehicle as well. The charge pipe kit is easy to install with commonly available tools and it is backed by AEM’s Lifetime Limited Warranty.
