OK, What the hell is this?
« on: 03:39:55 AM / 21-Feb-11 »
I saw this on an automatic CA20E MK I today, google was stupid, no help and my link for Nissan part does not comply.

Right in front of drivers strut tower next to air cleaner.

I keep my car cleaner then my room
Fuck you then, I'll take my movies, box of chocolates, bottle of wine and chloroform somewhere else.
Adding an SSD to that is kinda like strapping a 3 inch stainless HKS exhaust on a geo metro.

Emissions crap... Probably keeps the FPR from seeing vacuum for a little bit on startup, as a sort of hack-job afterstart enrichment.

+1 to what matt said. its the control module for the FPR control solenoid which just blocks the FPR from seeing vacuum.  the whole setup is bs and can be deleted
