I had the same issue and I also had to unscrewed the extended 02 bung and install the 02 senors without it. More then 1200 miles with the ERZ HFC and one night at the Drag Strip still NO CEL!

Guys,

I'm planning on getting ERZ HFC for my 2010 G37 and was wondering if you had a picture of 02 bung that you had to modify? Has ERZ fixed the problem with the 02 bungs? The word is spreading on myg37forum...

Thanks,

I had this same issue with the HFC's I received a couple weeks ago. Pretty silly to put O2 extenders that don't fit our O2 sensors.

yep same issue here but I just took them off and put some steel wool in there and no cels to date.

So the 02 sensors are not attached and the holes are just plugged?

I just put some steel wool in the regular O2 sensor bung and didnt use the extenders as they are the wrong size and screwed in the sensors. The wool acts as a filter basically.
