intake systems Topic is solved
You can get them for as little as $25, and as much as $250. They do nothing for the vehicle, and most will actually *hurt* performance.
I tried the K&N intake as well as the Injen intakes and both resulted in a *LOSS* of power.
The Euro Sport Tuning cold-air intake showed no noticable improvment, but no noticable loss, either.
Overall these intakes are worthless. The problem is simple: The stock airbox is actually VERY large, and there is a ram-jet that force-feeds cold air into the airbox when traveling at speed. A new intake, utilizing a cone filter will take in more air, but it takes in more air of a signifigantly increased temperature. The location of the throttle body, turbo (if equipped) along with the design of the engine bay and placement of the intake and exhaust manifolds provides for a LOT of heat-exchange into the intake air. The raised temperature will offset any gains of the increased airflow. You will notice a very profound drop in performance and fuel economy.
I highly recommend keeping the stock airbox, and using a high-performance air filter, such as the Amsoil.

Matthew is correct about a cold air intake, and if you are thinking about an aftermarket intake like for Honda's, don't bother. Honda's have very restrictive airboxes so any change makes a difference. Volvo 850's, I have read have very good airboxes, so the only real improvement you can do is get more air to it to keep it pressurized. Found on the front page of this site is a "Cool Volvo airbox mods". This will show you how to plumb basicilly a dryer exhaust hose from the front of your car through the transmission lines and to the airbox. Make you sure you follow Matthews advise and buy a High performance air Filter.
I'm not sure if you understood Matthew's explanation of a cold air intake, and why it won't work on your 850. Cold air intakes are just that, cold air. The colder the air the more power your engine can make. Turbo chargers are driven by exhaust. On turbo charged engines if you stay on them long enough the turbos will glow red hot. So, how cold is that air going to be once it passes through the turbo? Not very. Some of the Subaru and Mits EVO owners have found that by spraying water, and now CO2, on the intercooler they can reduce the temperature of the charged air going into the motor, equaling more power. Pick up one of the Turbo magazines and read how to do that to your car if you want to see a increase in power.
