I have seen posts about the stage 1 tune but my main questions are regarding plugs and air filter, haven't found that info.

I think I am ready to go with the BMS Stage 1 tune from either BMS direct or Extreme Power House. I don't want to do a flash at this point because I have to deal with the California Smog check starting in Jan. Not looking at DP at this time also due to smog.

From what I have read the BMS stage 1 works with a completely stock N55. I have done the following

VRSF Charge Pipe
FTP Boost Pipe
MST Turbo Inlet
VRSF Intercooler
Replaced the Coolant outlet hose and Mickey mouse flange.
Replaced plugs with Bosch ZR5 OEM plugs

So I'm not sure at this point if I need to go with the NGK 97506 colder plugs and if a dry drop in air filter would make a difference (don't want to mess with oiled), currently using Mann OE filter. Appreciate any advice
