Product Description
Overview
This L5P intercooler pipe and boot kit replaces the factory hot-side and cold-side charge piping on 2017–2019 Chevrolet and GMC 6.6L Duramax trucks. The kit uses 3-inch piping in place of the factory 2.5-inch pipes and removes the hot-side resonator for a less restrictive charge-air path.

- Reinforced silicone boots use an oil- and heat-resistant inner liner.
- Constant-tension T-bolt clamps maintain clamping pressure through heat cycles.

- Two sensor bungs can be drilled and tapped for additional boost or temperature sensors.
