Ram Air Intake for Geo Prizm (1990-1997) 1.6L 1.8L Engines

Improve Throttle Response and Efficiency for the Toyota A-Series Powered Geo Prizm

Who It’s For: Designed specifically for Geo Prizm and Toyota Corolla owners running the legendary Toyota A-Series engine family (4A-FE and 7A-FE). Whether you are maintaining a high-mileage daily driver or refreshing a classic commuter, this intake is for the owner who wants a bit more spirit out of their inline-four.

The Problem: The Toyota A-Series engines are world-renowned for their 300,000-mile longevity, but the factory air intake system is a major bottleneck. The stock plastic airbox and baffled resonator tubes are designed to prioritize silence over flow. After decades of heat cycles, the original rubber accordion hoses often crack, leading to vacuum leaks and poor idle quality. The factory setup effectively chokes the engine’s ability to breathe during highway merging and uphill climbs.

The Solution: We engineered this Ram Air Intake to replace the restrictive factory plumbing with a high-flow mandrel-bent pipe and a low-restriction cone filter. By smoothing out the induction path, we reduce turbulence and allow the A-Series engine to pull in a higher volume of air with less effort. This corrects the factory design flaws, delivering more consistent power and a much-needed improvement in throttle sensitivity.

Why This is the Ultimate Upgrade

• Better Volumetric Efficiency: By removing the baffled resonators, your engine doesn’t have to work as hard to pull air into the intake manifold, resulting in a more linear power band.
• Bulletproof Construction: The aluminum piping won’t crack or dry-rot like the factory rubber hoses, ensuring a lifetime of leak-free performance.
• Maintenance Simplicity: Features a washable and reusable performance filter, meaning you’ll never have to buy a paper replacement filter again.
