We utilize high-grade Cast Aluminum, Billet Aluminum, and T-304 Stainless Steel to solve common OEM issues: cracking, warping, and heat soak.

Engine-Specific Upgrades: Find Your Solution 1.1 6.7L Cummins Intake Horns (2007.5-2024) The stock intake horn on the Dodge Ram 6.7L Cummins is notoriously restrictive.
