Flashark 3.5" Stainless Steel Intake Manifold — 2007–2018 Dodge Ram 6.7L Cummins

Your factory intake manifold is a bottleneck. It was designed to meet emissions standards and pass cost targets — not to flow air. This Flashark 3.5" stainless intake manifold opens up the inlet and runs it into two 3" mandrel-bent tubes, giving your 6.7L Cummins more air volume per cycle, lower exhaust gas temperatures, and a noticeable improvement in fuel economy.

Built from mirror-polished stainless steel. Direct bolt-on to the factory 6-bolt head pattern. No cutting, no fabrication, no adapters.

⚠️ Off-road / track use only. Verify local emissions regulations before installing.

Key Features

• 3.5" inlet → dual 3" mandrel-bent outlets — expands airflow path where the factory design restricts it most
• Mirror-polished T-304 stainless steel — withstands heat cycling, corrosion-resistant, no coating to peel or flake
• 2× NPT ports — pre-tapped for boost gauges, EGT sensors, or IAT sensors, no drilling required
• Factory 6-bolt pattern — drops straight onto the stock head, seals tight, no modifications to the engine
• EGT reduction of 50–200°F — verified by Flashark testing and consistent with real-world owner data
• Fuel economy gain of 0.5–1 MPG — less restriction means less fuel needed to make the same power
• Compatible with stock and upgraded intercooler systems — pairs directly with 3" cold-side pipes
