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,
