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. 

We recommend replacing the v-band clamp while installing the O2 housing since they are a common failure point.
