Re: [DML] Volvo valve in air intake

[DMCVegas@xxxx]

Yes, it does cause a restriction. Even on the DOC UK's web site they 
mention that one of the modifications performed for the free flow 
exhaust system is the removal of this component. One of the things 
that I did to my car was I removed all the intake plumbing and 
ducting. Now I just have a flexable intake hose connected between the 
filter box and the intake mounted in the pontoon. It does indeed make 
a differance. While I'm not exactly able to outrun every other car on 
the road just yet, the engine does appear to breath a bit easier. The 
throttle does respond a bit quicker, but the imporvement by itself 
isn't something that I would brag that much about.

If you are looking to keep your car stock, or you live/operate your 
car in a cold climate, you're best to leave the assembly in place. If 
you're looking for little things you can do to help your car out, 
this may be one of them.
