Banks massive 3.5" boost tubes are the largest on the market, flowing 26-45% 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. Banks 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 just 3.0 inches, and your factory pipes are only 2.5 inches with crushed bent corners and flimsy plastic components. By contrast, Banks Boost Tubes are made of high-quality aluminized steel for maximum strength and durability. With Banks Boost Tubes' smooth bends, your turbo can spool quicker thanks to improved boost pressure retention for maximum horsepower. The Boost Tubes work with the stock Duramax intake components by using proprietary high-strength 5-ply silicone hoses. Unique to the 2020+ model, a pair of billet aluminum cold-side adapters are also used for the intercooler connection and the throttle body. These are specially made for the airflow requirements of the L5P and feature a Venturi-like taper on their inside diameter to maintain boost pressure and volumetric flow.Key Features: Huge increase in size and flow over stock and competitors (3.5" vs 2.5").Hot Side flows 490 CFM @ 12" vs stock 388 CFM. Cold Side flows 635 CFM @ 12" vs stock 435 CFM. Constant 3.5in diameter tubing for the best flow. Billet venturi couplers maintain boost pressure. Mandrel-bent aluminized steel construction. Allow the turbocharger to spool up faster. Spring-loaded constant tension clamps. Improves airflow by over 26% and 45%. 5-ply heavy-duty Nomex woven silicone couplers.

Best bang for your buck kit!
Can’t beat the price by any means. Total rebuild kit for Mercury 115 outboard for less than half the price and all high quality parts nothing cheap about this kit at all except the price. Highly recommend
