Ram Air Intake For GMC Envoy/Oldsmobile Bravada (2002-2005) with 4.2L L6 Engine Black

Maximize Throttle Response: Ram Air Intake for GMC Envoy & Oldsmobile Bravada with the Vortec 4200

Who It’s For: Designed specifically for GMT360 platform owners running the Atlas LL8 (Vortec 4200) inline-six engine who want to bridge the gap between stock utility and performance efficiency.

The Problem: The factory air box and resonator on the Vortec 4200 are notorious for being restrictive "suitcase" designs. Engineered for silence rather than flow, the stock setup forces air through multiple baffled chambers, which increases intake temperatures and kills the natural power band of this sophisticated DOHC engine.

The Solution: We engineered this Ram Air intake to provide a direct, high-velocity path to the throttle body. By eliminating the factory baffles, we allow the Vortec 4200 to breathe freely, correcting the sluggish low-end response and delivering a much more aggressive engine note when you step on it.

Why This is the Ultimate Upgrade

• Enhanced Airflow Velocity: Increases air volume and speed into the manifold, resulting in noticeable gains in horsepower and mid-range torque.
• Durable Synthetic Filter: Features a high-flow, washable pleated filter that stops more debris than paper units while offering significantly less resistance.
• True Bolt-On Fitment: Designed to utilize factory mounting points, making this a straightforward installation that can be completed in about an hour with basic hand tools.
