The Dirty Diesel Customs 3" High Flow Intake Y-Bridge, famously known as the "Double Rainbow," is engineered to maximize airflow and performance on your 2017–2019 Duramax. Precision-machined with a 3" to 2.5" billet Y and 2.5" tubing runners, it delivers a significantly smoother and more efficient intake charge to your truck.
We recently re-engineered the Double Rainbow to provide even cleaner flow by reducing total welds and refining the flange transitions for seamless air transition. The updated design features an improved MAP sensor fitment and a sleeker billet finish. This bridge is fully compatible with OEM components and most aftermarket piping kits, connecting directly to your factory intercooler piping or throttle valve.
The matching intake horn is available on our site as well.
