Seal the Boost the Factory Pipes Lose

Factory charge-pipe connections and boots give up under boost and heat, and a leak costs you power, raises EGTs, and adds turbo lag. These cold-side and boost-tube intercooler pipe upgrades seal the charge air so the boost actually reaches the engine.

Fits these trucks

  • GMC/Chevy 6.6L Duramax — LB7 (2004.5–2005 bridge & cold-side), L5P (2017–2019 cold-side, 2020–2024 boost-tube kit)

Frequently Asked Questions

Why upgrade the intercooler pipes?
The factory connections leak boost under load — you lose power and boost and see higher EGTs and turbo lag. Upgraded pipes seal the charge air.
What's a boost-tube / cold-side pipe?
The piping that carries cooled, pressurized air from the intercooler to the engine. Upgraded versions hold boost better than the factory setup.
Will it fit my truck?
