O2 Housing/Downpipe 1.4L
This product is currently out of stock.
*Ships in 3-4 day
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: This O2 housing does not include a catalytic converter, we move the cat to our mid pipe if you have a Cruze, if you do not install our midpipe or 2nd cat section with this product it will set check engine light without ECU programming. If you have a Sonic, you will require tuning to not set a check engine light.
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.
We recommend replacing the v-band clamp while installing the O2 housing since they are a common failure point.
DOES NOT FIT GEN 2 CRUZE.
Verified fitment on 1.4L Turbo Vanderhall Venice.
Updated 8.25.2020 to no bracket and includes flex section.
We are currently offering $60 in store credit to purchase your stock catalytic converter back from you (only the primary cat on the 1.4, not the mid-pipe). If you're interested, take a photo of your stock downpipe and email it to Henry@zzperformance.com. We will provide prepaid shipping labels for domestic (U.S.) shipments.
