Stillen HFC vs. BERK HFC

RCZ · 04-14-2009, 04:47 PM

aww you missed the unicorns part.

I would assume that is a possibility. I assume the non-foulers purpose is to take the sensor out of the direct flow of the exhaust gas, which would cause it to miss read and trigger the cel? I am not sure about this, I have always just assumed this was the reasoning. I also assume the steel wool is there to create even more of a barrier (yet allow it to pass enough gas through to the sensor) while not melting under the high temperatures of the exhaust gas.

Right?

This is the reason why Berk and others have decided to create out-of-flow adapters for the o2 sensors (built in non-foulers). This is the reason why I am assuming Stillen's HFC will have this feature as well, perhaps evolved in one way or another to keep it from affecting flow.

Careful with the O2 sensor Semtex, it is very easy to damage them, they are sensitive.

Stillen's HFC doesn't have this feature. Have you seen them yet? They're up on their website with pics. Available for sale. That's how this whole side-discussion got started -- I pointed out the lack of this 'feature' on the Stillen HFCs, which means they'll need anti-foulers. Some folks chimed in and said that even with Berk's built-in extensions, you still might get CELs, hence the steel wool.

And expensive.

Apparently O2 sensors are female!
