The Banks 25993 Boost Tube System will get the turbo spooling faster in your 2013-2016 GM 6.6L Duramax LML. These higher flowing tubes retain more boost pressure between the turbo, intercooler, and intake which results in maximum horsepower. The included 4 and 5-ply heavy-duty silicone couplers combined with spring-loaded constant tension clamps for a tight, reliable hold under high boost conditions. Banks hot and cold side tubes are constructed from a high-quality mandrel bent 3.5" aluminized steel tube for a smooth constant diameter and have up to 105% greater flow area versus the stock tubes.

Note: This kit is designed to work with the stock intercooler or aftermarket intercoolers with stock inlet and outlet sizes.
