Give your Cummins the massive gulp of fresh air it truly craves by swapping out restrictive factory piping for this heavy-duty 3.5-inch mandrel-bent setup. The integrated Cross-Air design smartly routes cool airflow directly to cylinders 1, 5, and 6 to balance cylinder temperatures and slice through high EGTs.

Expect punchier throttle response, faster turbo spool-up, and noticeably improved fuel efficiency on every drive. Fully TIG-welded and packaged with premium 5-ply silicone couplers and stainless T-bolt clamps, it is built tough to handle high boost with a grin.
