Wehrli 17-19 Chevrolet 6.6L L5P Duramax Passenger Side 3.5in Intercooler Pipe - Gloss Black

Maximize charge air efficiency on your 2017–2019 Chevrolet Silverado HD or GMC Sierra HD with the Wehrli Custom Fabrication Passenger Side 3.5-inch Intercooler Pipe in Gloss Black for the 6.6L L5P Duramax diesel. This mandrel-bent aluminum intercooler pipe delivers a full 3.5-inch bore — larger than the factory plastic tube — for improved airflow, reduced charge air temperatures, and more efficient turbo operation across the RPM range.

The Gloss Black powder coat is clean, bold, and corrosion-resistant, giving your engine bay a factory-plus appearance. Wehrli includes silicone couplers and T-bolt clamps for a boost-leak-free installation, and the pipe fits directly in place of the factory unit with no modification. Built in the USA by a brand trusted by Duramax diesel enthusiasts worldwide.

  • Passenger side 3.5-inch intercooler pipe — larger diameter for superior airflow over stock
  • Mandrel-bent aluminum — precise, smooth bore for maximum charge air flow
