Give your Cummins the airflow it craves with this fully TIG-welded, mandrel-bent 3.5-inch steel driver-side intercooler tube. It teams up seamlessly with your factory or stock-location intercooler to unlock quicker turbo spool and crisper throttle response.

We have packed in heavy-duty 5-ply silicone couplers and stainless T-bolt clamps so you can bolt everything up in no time. Enjoy lower exhaust gas temperatures and a happier, harder-working diesel beast on every drive.
