Our driverside intercooler tube for the 2007.5-2009 Cummins 6.7L is built around 3.5" mandrel bent, .060" thick steel tubing. Installing this intercooler pipe increases air flow by 35% over the factory 2.4" ID plastic intake plumbing. Install is simple and straightforward, with all new couplers and clamps provided.

Some competitive products require you to cut the factory steel band off your stock tube in order to save the factory outlet boot. Instead we provide heavy duty 5-ply silicone couplers and stainless T-bolt clamps, which makes install is simple and straightforward. Just loosen the factory clamps and install the supplied parts. Full-color instructions with photos are provided.

Intercooler Compatibility: This product was designed to work with the factory intercooler, and as such will work with aftermarket intercoolers that mimic the factory inlet / outlet locations. If you have an aftermarket intercooler that differs from that, please call for compatibility.
