yah, this articles was good, but my mod was even simpler, just 2 holes and dryer tubing in between.

You just made my job easier. I was looking at doing something similar. I didn't want to butcher the Air box in my 97 960 to get more air. I was thinking of running a tube made of PVC under the factory snorkel and into the box. Kind of like an additional stealth intake hidden by the factory unit. I never thought of using plastic hose or two. Thanks you just save me a lot of work. As soon as I can find another air box to cut up for this install I'll be good to go.

I plan on doing this soon.

On my 740 airbox at the bottom it has the one tube going from the box out the side fender to get it's air. directly opposite of that is another outlet that has a barrier held in place by a screw. I plan on running a hose from that to someplace in front of the car behind the grill to pick up additional cool air while I drive.
From the looks of it, I shouldn't need to cut my airbox at all!

Hehe yeah sorry for the zombie resurrection of this thread. I would do it like the OP's article, accept that without some sort of pics. I really can't tell what he has done based on his description alone. If somebody has pictures of this mod, I would be much obliged.


I based my own idea of this off of what I can see with my airbox having had it all apart.

Dump the air box, get a cone, feed cold air to it, done. Not much for improvment but fairly easy.

Has everyone used pipe? I found that 2.5" is the perfect size though it is hard to find. How are people blending it into the box?

At best you can negate the drag made by the filter - not one dyno test proves it makes for 1HP

Cold air - yes but Volvo 740s have that already! Adding accordian hose to intake?!? that will just create more turbulent airflow.

RAM AIR DOES NOTHING ON A CAR - DOESN'T TAKE AN ENGINEER TO FIGURE THIS OUT

No more replies to this thread unless you can dyno / track prove me wrong!

cold air is good, period. the intercooler removes a percentage of heat from the air, not a set number of degrees. start with colder air, end with colder air

If ram air does nothing on a car then why are so many race cars using it to feed their engines? Hmmmmm. "DOESN'T TAKE AN ENGINEER TO FIGURE THIS OUT"

Ram air does not work on a dyno, the car needs to be moving. "DOESN'T TAKE AN ENGINEER TO FIGURE THIS OUT"


And colder air = denser air = more HP potential. "DOESN'T TAKE AN ENGINEER TO FIGURE THIS OUT"

He really should diversify his information resources before he makes statments he expects to be taken as fact. And the sad thing is that he was trying to sound smart. He probably still thinks he is right because someone who claims to know something about this told him that it doesn't work.
