Cold Air Intake for Chevrolet Cobalt (2005-2007) 2.0L Supercharged Engine

Increase Boost Efficiency and Supercharger Whine on Your Ecotec LSJ Powered Cobalt

Who It’s For: Designed specifically for 2005-2007 Chevrolet Cobalt SS owners running the supercharged 2.0L Ecotec LSJ engine.

The Problem: The factory air box on the Ecotec LSJ is a major bottleneck. It was designed more for sound suppression than performance, utilizing a restrictive plastic housing and a thick paper filter that chokes the Eaton M62 supercharger. This restriction increases intake air temperatures and prevents the blower from reaching its full potential, while also completely masking that iconic supercharger whine enthusiasts love.

The Solution: We engineered this Red Cold Air Intake to replace the restrictive factory plumbing with lightweight, mandrel-bent T304 aluminum. By smoothing out the induction path and utilizing a high-flow washable filter, we significantly reduce pumping losses. This allows your supercharger to breathe deeper, improving throttle response and delivering a much more aggressive engine note under boost without voiding your factory warranty.

Why This is the Ultimate Upgrade

• Dyno-Proven Gains: Engineered to increase horsepower and torque by up to 10% by allowing the supercharger to pull air more efficiently.
• Premium Construction: Built from T304 lightweight aluminum piping which dissipates heat faster than stock plastic, finished in a durable red powder coat for a custom engine bay look.
• Signature Sound: Removes the factory resonators to finally let the Ecotec LSJ engine’s supercharger whine be heard clearly during wide-open throttle.
