The Dirty Diesel Customs 3" High Flow Intake Y-Bridge, also known as the Double Rainbow, is built to maximize airflow and performance on your 2017–2019 L5P Duramax. Precision-machined with a 3" to 2.5" billet Y and 2.5" tubing runners, it delivers smoother, more efficient intake flow while staying fully compatible with OEM parts and many aftermarket piping kits. It connects directly to your factory intercooler piping or throttle valve and is available for both emissions-on and off setups.

We recently re-engineered the Double Rainbow to make it even better, reducing welds for cleaner flow, refining the flange transitions for seamless airflow, and updating the MAP sensor fitment. The billet Y has also been redesigned for a sleeker, more refined finish that looks as good as it performs.
