was looking at some stuff on the web and came across this pic.
noticed the pipe coming from the air filter box to the front of the car.
what do you make of this?
has he cut a hole above the filter and fitted a small cold air feed?

Its not a cold air feed mate, its the pipe from the Air Pump. It pumps exhaust gasses into the intake for emission control purposes (I think).
My 850 had one (until I removed it). Not sure what engines it was fitted to though.

its a secondary air system AKA SAS

oh right. never seen that before. thought id ask.
a better pic
My cousins V70 T5 has the same airbox (with the hole in the top) but with a bung to block it off.
I removed mine after the pump mountings broke (thin rubber things), and all its associated pipework, it was bloody heavy. All the control relays are still connected, so that the ecu doesn't throw a code.

Volvo call it the 'Pulsed secondary air injection system' or 'PAIR'

Well, its supposed to do something to the exhaust emissions (lower them?), but put basically it pumps some of the burnt crappy exhaust gasses into the airbox which then goes through the MAF, turbo, intercooler, throttle body and back into the cylinders to be burnt again.
I'm not sure on its effect performance wise, can't be much, if anything at all, but its less shiz goin through the intake system.
