Banks Boost Tubes Add Response and Airflow

The Banks Boost Tube Upgrade Kits for 2017-019 and 2020+ Duramax L5P-powered GM trucks are the largest charge air cooler pipes in the industry, measuring a full 3.5” in diameter, a full inch larger than stock and half-inch larger than the closest competitor! These fully mandrel-bent pipes have a constant diameter and are capable of flowing 680 CFM versus the stock’s 364 CFM for an 87% increase in airflow, Your turbo will spool up quicker, the charge air will be cooler from the intercooler and EGT’s will drop.

And, the system includes CFD-designed billet coupler(s) to reduce turbulence and prevent cracking, which is common with the stock plastic units. L5P owners know all too well that a cracked coupler results in a boost leak which leaves you on the side of the road. Installation can be done at home with ordinary hand tools. The Banks Boost Tube Upgrade Kit is a must-have.
