Familiar with a cold air intake? Those increase the volume of the intake, subsequently pulling the sensor out of the air stream. The Eco-Block does the same exact thing, but does so by utilizing a spacer to pull the sensor out of the air stream. The benefits you receive with the Eco-Block vs. a cold air intake:
- A fraction of the price: $50 vs. hundreds.
- Maintains smaller intake volume, maintaining air velocity. The larger volume from an aftermarket cold air intake slows the air down, creating lag.
- Keeps the stock air box / intake in place, which keeps your car smog legal and warranty safe.
- Does not require a tune to maximize it's performance. 

*Only compatible with a stock intake and a stock tune, unless it's installed at the same time as a custom tune.
