People with HFC's: Did you throw a CEL after install
 

Yes or No

erz hfc no cel yet and I out some steel wool in.

I did a day after... but it was an installation error... the driver's side o2 wasn't tightened. Took care of that, cleared the code, and now I'm CEL-free.

I have the ERZ HFCs on my 2010 G37xS sedan. :)

Might help if you specify which HFC. Some have extended O2 ports. Some don't. And that might make a difference as far as CELs go.

i had bercs and had a cel from day one. my FI was good for about 5000km then got a CEL. in FI defence he had not shipped out the non foulers with mine and I had them on the shelf when the CEL light came on as of today 40,000 km no CEL.

i'm not going to vote because i did but only because my friend dropped the left hand sensor and broke the heater element

:iagree:

And No!

Zsteve and Efuseakay, do you guys have the extenders on?

Yup! Once the o2 was tightened.... No CEL!

Can the test pipe boys get on? ERZ RTP, no CEL.

I'm going with ERZ's with the extenders, I figure I could get angled defoulers if I need them

Your referring to the shorter one's that are included not the optional angled one's, right?

no extender here but some steel wool.

Nope.

Without an extender, where can you stuff the steel wool?
