The SPOOLOGIC Intercooler Pipe Kit SL-410-035 is a complete mandrel-bent aluminum charge-air-cooler pipe replacement for 2020-2026 Chevrolet Silverado GMC Sierra 2500 3500 6.6L Duramax L5P. Hot-side and cold-side pipes, 5-ply silicone boots, and T-bolt constant-tension clamps — everything required to eliminate the factory plastic intercooler pipe failure mode permanently.

Factory intercooler pipes on tuned or worked diesels crack, split, and pop off boots under sustained boost. The plastic can't take the heat cycling, and the OEM worm-gear clamps lose tension the first time the pipes cool down. SPOOLOGIC's aluminum kit fixes both problems at once with corrosion-proof mandrel-bent tubing, 100 PSI-rated 5-ply silicone boots, and T-bolt clamps that hold their torque forever.

Common Factory Intercooler Pipe Failure Symptoms

If your truck is showing any of these symptoms, the factory intercooler pipes are most likely the cause:

• Boot blow-off under hard acceleration — worm-gear clamps lose tension after a few heat cycles and let the boot pop off the pipe
• Cracked or split cold-side pipe — the factory plastic can't handle sustained boost pressure and cracks at the tightest bend
• Pinhole leaks with hissing under boost — heat cycling embrittles the plastic until it splits along a molded seam
• Loss of boost pressure and reduced power — even a small leak bleeds off enough boost to trigger EGT spikes and reduce fuel economy

Why Mandrel-Bent Aluminum Outlasts OEM

The factory intercooler pipes are molded plastic — cheap to produce, easy to shape, and guaranteed to crack under sustained boost. SPOOLOGIC pipes are mandrel-bent from aluminum tube, which preserves the full cross-sectional area of the tube through every bend (no flat spots or wrinkles that choke airflow), tolerates heat cycling without embrittling, and doesn't blister from oil-saturated CAC plumbing. Powder-coated finish resists chemicals and UV; 5-ply silicone boots with embedded reinforcement fibers hold over 100 PSI without ballooning; T-bolt constant-tension clamps apply even 360° pressure and don't back off in service.

What's Included

• Mandrel-bent aluminum hot-side and cold-side intercooler pipes
• 5-ply silicone CAC boots
• T-bolt constant-tension clamps for every connection
• All hardware required for a complete installation

1-Year Limited Warranty

Every SPOOLOGIC intercooler pipe kit is covered by a 1-Year Limited Warranty against defects in materials and workmanship from the date of purchase. Warranty coverage requires that the kit first be shipped back to SPOOLOGIC for inspection. If SPOOLOGIC determines the failure was caused by a defect in materials or workmanship, the affected component will be replaced at SPOOLOGIC's discretion. Warranty does not cover damage from improper installation, over-tightened clamps, use outside the listed fitment, damage caused by a failing turbo or intercooler, punctures or cuts from foreign objects, corrosion from prolonged salt or coastal exposure once the aluminum finish is chipped or gouged, cosmetic wear, or normal darkening of the anodized finish under heat. Warranty does not cover labor, shipping, towing, downtime, gaskets or clamps consumed on subsequent removal, or any other costs outside the kit itself.
