Short Ram Air Intake For Isuzu Impulse/Geo Storm (1990-1993) with 1.6L 1.8L L4 Engine Black

Improve High-RPM Breathing for the Isuzu Impulse & Geo Storm 4X-Series

Who It’s For: Designed specifically for 1990-1993 Isuzu Impulse and Geo Storm owners running the Isuzu 4X-Series engine family.

The Problem: The Isuzu 4X-Series is a high-revving gem, but the factory intake system is its biggest bottleneck. Between the restrictive air box and the corrugated plastic intake hose, the engine struggles to pull in enough air at the top end of the power band. This causes significant air turbulence and heat soak, especially during spirited driving on these classic pocket rockets.

The Solution: We engineered this short ram intake to replace the restrictive factory plumbing with smooth-bore, T304 lightweight aluminum. By streamlining the air path directly to the throttle body, we’ve corrected the factory design flaws of the 4X-Series, delivering much faster throttle response and a more aggressive induction note that matches the car’s 90s heritage.

Why This is the Ultimate Upgrade

• Enhanced Induction Flow: The T304 aluminum piping provides a smooth internal surface, reducing air drag and allowing the engine to reach its power peak more efficiently.
• Maximum Durability: Unlike the factory rubber hoses that crack and leak air over time, this aluminum setup resists heat and maintains its structural integrity for the life of the vehicle.
• Direct Bolt-On Fit: Designed for the M-body and S-chassis engine bays, this kit installs in under an hour with basic hand tools and requires zero permanent modifications.
