Improve 1NZ-FE Efficiency and Throttle Response for the Toyota Echo
Who It’s For: Designed specifically for 2000–2005 Toyota Echo owners running the 1NZ-FE engine family who want to wake up their daily driver or autocross build.
The Problem: The stock intake on the 1NZ-FE is built for one thing: silence. The factory air box uses a series of baffles and corrugated plastic tubing that creates massive air turbulence and restricts flow. This restriction forces the engine to work harder just to breathe, which results in sluggish throttle response and a flat power curve in the mid-to-high RPM range.
The Solution: We engineered this intake to eliminate those factory bottlenecks. By utilizing mandrel-bent T304 aluminum piping and a high-flow conical filter, we provide a straight-shot air path to the throttle body. This reduces intake air temperatures and allows the 1NZ-FE to pull in a higher volume of oxygen, delivering a noticeable improvement in how the car reacts when you tip into the gas.
Why This is the Ultimate Upgrade
-
Optimized Airflow: Increases horsepower and torque by up to 10% by reducing the pumping losses inherent in the restrictive factory assembly.
-
High-Grade Materials: Constructed from T304 lightweight aluminum for superior heat dissipation and long-term durability compared to stock plastic.
-
Straightforward Bolt-On: This is a true direct-fit system that installs in under 60 minutes with basic hand tools; no cutting or permanent modification to your chassis is required.
