O2 Bung Extender

$24.99

This product is currently out of stock.

This will reduce the chance of getting a CEL for running a high flow cat in your car. It is made from Stainless steel, has straight and a 90 degree bend so you have two options for a more indirect flow of exhaust gasses to the rear o2 sensor. The 90 degree extender angle is adjustable so it can fit in any position.
We do not recommend running without the rear o2 sensor because it could run the rear o2 test and reduce your gas mileage.

Fixed my Check Engine Light!

Ordered the Turbo Back Kit for my 2020 Sonic RS and threw it on and as expected the check engine light came on. Ordered this, installed it in 5 min and after driving it for a day or two the check engine light went off!

O2 **** Extender

Worked well. Originally I installed the ZZP catted downpipe and the O2 sensor was smashed up against the heat guard wall which caused the wires to be exposed and short out causing CEL. Installed this item and wrapped the wires. Works perfect now and no CEL. Product works great and easy to install. Only thing is they should recommend this with the downpipe initially. Would have saved me from removing and installing downpipe twice. But ZZP puts out great quality products.
