Increases throttle response and reduces turbo lag Polished (Set) FOR 2017-2019 CHEVY/GMC 2500/3500 6.6L DURAMAX, L5P Core Auto’s massive 3.5in boost tubes are the largest charge air cooler pipes on the market, flowing 680 CFM and 87% more air than stock! Smooth mandrel-bent tubes deliver more air to your engine while reducing boost pressure loss resulting in quicker turbo spool and more power. Specifications Our Boost Tubes are the largest charge air cooler pipes in the industry measuring in at a full 3.5 inches. Every other competitive product on the market tops out at 3.0 inches, and your factory pipes are only 2.5 inches with crushed bent corners and flimsy plastic components. By contrast, our Boost Tubes are made of high-quality stainless steel for maximum strength and durability. With these Boost Tubes' smooth bends, your turbo can spool quicker thanks to improved boost pressure retention for maximum horsepower.
