The factory o2 housing on the 1.4 turbo Ecotec motor has been shown to be quite restrictive. Our 2.5" Stainless steel high-flow version has been dyno proven to produce gains of up to 8 horsepower at the wheels. This is a gain of more than 6 percent! This easy bolt-on modification re-uses the factory V-band clamp where it attaches to the turbo. Comes with everything needed to install just replacement bolts and nuts. Dec 2014: It comes with 2 o2 bungs, and a plug in case you want to add a wideband o2 sensor later. 

Note: The ZZP O2 housing does not include a catalytic converter and will set check engine light w/o ECU programming.

For a complete street setup that does not require ECU programming, see our O2 housing/mid pipe combo. This part fits the 1.4 Chevy Sonic, Cruze, and Buick Encore.
