Performance Air Intake for Buick Roadmaster (1994-1996) 4.3L 5.7L Engine

Increase Airflow and Throttle Response for the Buick Roadmaster LT1 & L99 V8

Who It’s For: Designed specifically for 1994-1996 Buick Roadmaster owners running the LT1 and L99 V8 engine family who want to eliminate the restrictive factory resonators and improve engine sound.

The Problem: The stock intake system on the LT1 and L99 engines is cluttered with plastic resonators (often called "home plate" and "first base" by enthusiasts) that are designed for silence, not flow. These components create massive air turbulence and are prone to heat soak, which kills throttle response in these heavy B-Body cruisers.

The Solution: We engineered this intake to replace the bulky factory baffling with mandrel-bent T304 aluminum piping. This provides a high-velocity, direct path for air to reach the throttle body, correcting the factory design flaws and allowing the LT1 to finally breathe the way it was intended from the factory.

Why This is the Ultimate Upgrade

• Enhanced Induction Flow: By removing the baffled factory tubing, you can see gains of up to 10% in horsepower and torque by reducing pumping losses.
• T304 Aluminum Construction: Unlike cheap plastic kits, our T304 lightweight aluminum piping dissipates heat faster and provides a permanent solution to the aging, brittle factory rubber boots.
• Serviceable Filtration: The included high-flow filter is fully washable and reusable, only requiring maintenance every 50,000 miles, which saves on long-term maintenance costs compared to paper filters.
