2017-2025 Duramax L5P Intercooler Pipe Boot / Coupler W/ Clamps - Off the Turbo

This upper boot is a direct replacement for the factory hot side / driver side intercooler pipe on the 2017-2025 Duramax L5P Silverado / Sierra 2500/3500HD 6.6L. It comes off the turbo outlet and meets the intercooler pipe on the driver side (See first picture for example). Both t bolt clamps are included as shown in the photos! This may work on 2026 trucks as well, but we are working to confirm that.
 
Even if yours hasn't ripped or torn yet, this is something you'll want to grab and stick in the glovebox for when it does happen! This is not a standard size that can be purchased at the auto parts store and something we have custom made for us! GM does not sell the boot separately and makes you purchase the whole pipe, which costs over $800!
 
We keep these in stock and ready to ship at all times! Expedited shipping options can be selected during checkout!
 
If you have a 2017-2019 Duramax, we offer a lower boot and clamps as well which can be found here - L5P Replacement boot with clamps
 
If you have an aftermarket intercooler pipe, such as WCFAB, we sell those HERE
