Cold Air Intake for Pontiac Firebird Formula (1988-1989) 5.0L 5.7L Engines

Wake Up Your L98 Small Block Chevy with This High-Flow Firebird Formula Intake

Who It’s For: Designed specifically for 1988-1989 Pontiac Firebird Formula owners running the legendary Small Block Chevy engine family, including the 305ci (5.0L) and 350ci (5.7L) variants.

The Problem: The factory air box and corrugated plastic intake bellows on the Small Block Chevy equipped F-Bodies are notorious for heat soak and air turbulence. By the time oxygen reaches your throttle body, it’s been heated by the engine bay and slowed down by the ribbed factory tubing, which is a major bottleneck for the Tuned Port Injection (TPI) runners that rely on high-velocity airflow.

The Solution: We engineered this intake to replace the restrictive, aging plastic with mandrel-bent T304 aluminum piping. By straightening the air path and utilizing a high-flow conical filter, we ensure your Small Block Chevy gets a consistent supply of cooler, denser oxygen, correcting the factory airflow deficiencies and letting the TPI system function as GM originally intended.

Why This is the Ultimate F-Body Upgrade

• Optimized Plenum Filling: By reducing intake turbulence, this kit helps maintain air velocity, which is critical for the long-runner intake manifolds found on these 80s V8s, resulting in improved throttle response.
• T304 Aluminum Construction: Unlike the factory plastic that becomes brittle and cracks after decades of heat cycles, our lightweight aluminum piping stays rigid and provides a much cleaner, show-quality look under the hood.
• True Bolt-On Engineering: This system is designed to work with your existing manifold setup. You can have the factory air box out and this high-flow system installed in under 60 minutes with nothing more than basic hand tools.
