So, what's the word on those? Anyone used those with CX5? Benefits/downsides?
Thanks
Why do you need one? Unless you have removed your CAT or run an aftermarket exhaust that is triggering a CEL, there is no benefit to installing one.
I did not say I need one. I was just curious what is the general opinion about those in here.

As Chris_Top_Her stated, they're really only used to spoof readings on custom exhaust setups/aftermarket manifolds. You either need one, or you don't, and they either work, or they don't. The only other measure is reliability/durability, and for that you'd need to compare 02 extenders from different manufacturers.
Maybe you meant to ask what an 02 extender does, since you didn't provide any specifics that would lead us to believe that you were looking for opinions on a particular 02 extender.
