Cold Air Intake for Pontiac Firebird (1990-1992) 5.0L 5.7L Engines

Maximize High-Velocity Airflow for your Third-Gen Firebird Small Block Chevy V8

Who It’s For: Designed specifically for 1990-1992 Pontiac Firebird (including Formula and Trans Am) owners running the legendary Small Block Chevy V8 engine.

The Problem: The factory air intake system on the 1990-1992 Small Block Chevy V8 was designed more for noise suppression than raw performance. Using restrictive, baffled plastic resonators and corrugated rubber ducting, the stock setup creates massive air turbulence and suffers from significant heat soak. This prevents your Tuned Port Injection (TPI) system from reaching its full volumetric efficiency, especially during spirited driving.

The Solution: We engineered this intake to eliminate the bottlenecks in the factory Small Block Chevy V8 air path. By replacing the restrictive stock boxes with a high-flow, mandrel-bent induction tube and a heat-shielded filter, we ensure a steady stream of oxygen-rich air reaches the intake manifold. This corrects the lazy throttle response inherent in the stock late-model third-gen F-bodies.

Why This is the Ultimate Upgrade

• Enhanced Volumetric Efficiency: By smoothing out the intake path, this system allows the TPI plenum to fill more efficiently, resulting in noticeable gains in mid-range torque.
• Thermal Management: The black powder-coated finish and oversized filter placement are designed to resist heat soak better than the stock plastic housing, keeping intake air temperatures (IATs) lower.
• Direct Bolt-On Fitment: Designed to utilize existing mounting points, this kit avoids the need for permanent modifications to your classic F-body engine bay.

Common Questions

Which Pontiac Firebird models and engines does this cold air intake fit?
This cold air intake is built for 1990-1992 Pontiac Firebird Formula, Trans Am, and Trans Am GTA models equipped with the 5.0L (LB9) or 5.7L (L98) Tuned Port Injection (TPI) Small Block Chevy V8 engine.

Does this fit the 5.0L L03 Throttle Body Injection (TBI) V8 or non-V8 engines?
This kit is engineered specifically for the front-facing throttle body setup on 1990-1992 5.0L LB9 and 5.7L L98 TPI V8 engines (rated from the factory at 210-245 HP and 285-345 lb-ft of torque).

Does installation require cutting or permanent modifications to the engine bay?
Installation is a direct bolt-on using existing factory mounting points, so permanent modifications to your third-gen F-body engine bay are not required.

How does this intake help with engine bay heat and airflow?
It replaces the baffled plastic resonators and corrugated rubber ducting with a smooth, black powder-coated mandrel-bent induction tube and an oversized heat-shielded filter to reduce turbulence and keep intake air temperatures lower.

What performance changes can I expect after installing this kit?
Smoothing out the intake path improves airflow into the TPI plenum for crisper throttle response, noticeable mid-range torque gains, and a deeper induction sound.
