Well I called ERZ and spoke with one of their sales reps. He told me that you can buy the angle anti-fouler separately at ERZ $34.99 a piece or $69.98 for the pair (Link Below) but said it was not part of the 370z HFC purchase. I also purchased my HFC after reading your review spearfish25, so maybe you got lucky it was included or maybe I just got unlucky it wasn’t.
Either way I am going to have it installed tomorrow with out the angle fouler extension and see what happens. If I throw a CEL light then hopefully ERZ will send me the anti-fouler extension. I just don’t want to pay for something I may not need.
