What's the deal with high0flow 02 sensors? Are they necessary when running a header/dp etc or is it just a marketing ploy? I ran a standard set of sensors when I had my ZZP combo in, and still do with my GMPP catback, but I plan on doing another header/dp, so I want to use them if necessary. Don't want to run totally off. I will just do the front as I will do HPT and do the rear 02 delete.. If they are suggested, how much more is a high-flow cost-wise in relation to the standard one?

Thanks!

 

High flow o2 sensor?....

The o2 sensors do not hinder flow...

 

I know that, but they advertise high-flow ones. I suppose that they can process the higher amount of airflow better?

 

You do not need to change out your o2 sensor... its just fine.

 

maybe u misunderstood high flow catalytic converter? no such thing as a high flow o2, stock ones are fine...

 

I'm 99% positive I've seen it..? lol Dunno.. My front one seems to be reading off at times, so i'll likely just replace the front, then just do the rear delete with HPT then..

 

Reading off? How so?
