Hi everyone,
I need some advice I just got HKS HFC PN: 33005-DM003 with HKS Down pipe I’m planning to use them with the stock cat back on my Evo X GSR 2011.
My question is do I need an O2 spacer for this HFC? I have the COBB AP an the plan is to use the stage 2 91ACN map v200, I read in this forum the stage 2 disables de O2 sensor but some people are still getting codes.
I’m going to install the HFC on Monday or Tuesday.
Any advice is appreciated
My mods so far:
COBB AP
HKS drop in filter
ETS UICP
Installation pending:
HKS DP
HKS HFC

Most likely.
I have a High Flow Cat with a secondary o2 de-fouler and still get P0420 codes every now and then.

I just got it installed today w/o the spacer flashed the stage 2 91ACN map did a couple pulls and so far no codes, but well I suppose they don’t show up immediately so I will wait and see.
