2017-2025 Duramax L5P Replacement Driver Side Intercooler Pipe Boot With Clamps!
WE KEEP THESE IN STOCK AND READY TO SHIP AT ALL TIMES! We understand the urgency and often times see customers expediting these which can be selected during checkout!
This is a John C Garage exclusive item! We offer a replacement silicone boot with heavy duty adjustable clamps for the upper connection of the factory driver side intercooler pipe where it meets the turbo on the Duramax Diesel L5P from 2017-2025. This has confirmed fitment on the Chevy Silverado and GMC Sierra 2500/3500HD 6.6L Diesel from 2017-2025 and we believe it may work on 2026 trucks as well, but we are working to confirm that. These boots are a custom size that we have manufactured and is not something that can be found in auto part stores! They utilize a 5mm thickness and rated for 95 psi of boost. We do offer a lower boot connection as well, but that is specific to the 2017-2019 Duramax L5P trucks!
We often see the OEM boots on these trucks rip over time causing a major boost leak! This can lead to serious performance and emissions related issues. Even if yours hasn't ripped or torn yet, this is something you will want to grab and stick in the glovebox for when it does happen! This is not a standard size coupler.
GM does not offer this replacement boot by itself! They make you purchase the whole intercooler pipe which will cost you over $800! We offer the upper boot for the 2017-2025 Duramax 6.6L and lower boot (Specific to the first gen 2017-2019 Duramax 6.6L) that are a direct fit of your factory boots. Each boot connection from factory uses a steel band clamp that is nonadjustable. These will need to be cut off with a dremel or cut off wheel. Our replacement boots include high quality T-bolt clamps to secure each boot and can be adjusted at any time.
We are working on the middle boot (Specific to the 2017-2019 Duramax 6.6L) and that will come later this year.
