cold air intake

chriskose · Post by **chriskose** » 17 Nov 2002, 16:48

Had a quick question about cold air intakes... who's had experience with them? Which is more prefferable K&N or Weapon R? What'd you pay? Performance? Sound?
I'm thinking of installing one but they seem to be a little expensive, maybe I can make my own....

An air scoop, right? I've thought about this and read about it, but nobody I've talked to has ever actually completed one, or completed one with a design they shared anyway.

There's two problems: plumbing and dirt/water intake

.

Plumbing is pretty self-explanitory... there's not tons of room nor a great path to follow. The other problem is how to avoid getting crap into the airbox without restricting the airflow significantly, a circumstance that would void any gains from this concept.

It remains a great idea, a type of 850 holy grail if you will, and one that I'd be willing to try after my laundry list of other more necessary work is done: flush coolant/replace t-stat; replace headlight wiper blades; rear shock mount replacement.

Please let us know if you start this or get anywhere on the specifics! Intersting subject for sure!

Air scoop? I was thinking more along the lines of a K&N or Weapon R cone filter mounted where the air box is. volvospeed has a section on it. I guess this would technically not make it a cold air intake. But now that I think about it, it may not be that hard.
I work in a machine shop and we mostly do plastic machining so parts, scraps and glue wouldn't be difficult to source for the p;umbing. I guess I need to take a closer look under the car for an appropriate mounting location.
As far as water and dirt is concerned, I've seen intakes on Hondas and the like that have a sort of shield on them to block stuff. But I can't recall exactly how they look.
One things for sure, I'm not going to pay $180 to do it.[/b]

Ah, then calling it a cold air intake is a bit of a misnomer... often the air under there is hotter than a stock setup, and performance can suffer in hotter months. "Open element air filter" would be more accurate. Mostly those who tried this have had mixed results: when you're moving power can be nice, but in city/slow traffic power and economy can suffer. All said the noise of air getting pulled in was noticible

.

I was talking of piping coming up from the front skirt/spoiler... perhaps thru one of those holes next to foglamps, then into an open element air filter or even the stock box with a K&N or Amsoil filter.

what about scrapping the airbox completely, plumbing straight from the throttle body down to somewhere near the charcoal canister. and put a pod filter on the end. completely away from any heat the engine puts out
thats also near the fog lamp hole for a colder airflow

I wouldn't be putting a pod/cone type in to replace the air filter box, as the air box gets its air from the front of the car, whereas a pod type one would simply be drawing in air from the engine bay, the air there would be hotter and if anything, you'd be getting less performance.
keep the air box and simply get a decent king dragon, or k&n type filter to replace the original style.

How would you go about building one?

I was told me a guy from Advanced Auto parts, that you can just scrap your old airbox, and put a cone filter on the end of the MAF, and it works just as good if not better then your normal airbox. You just have to measure the MAF flange so you can buy the right K&N cone filter, which I reccomened. I bought the K&N panel filter for my 850 sedan, and it worked wonders, for Tourque and Horsepower. I gained about 5 Hp after putting that panel filter in. So I am running 170 HP, and going to buy an exhaust in the next few weeks which should add about 10 HP, so I will be around 180 HP. I was also thinking next summer to do a new ECU which was told by the company about 10-20 HP gain, So with basically a stock engine with a new exhsut K&N cone filter/homemade cold air intake, and a new ECU I should be running around 200 HP which isn't bad at all for a non turbo Volvo 850 sedan.

is this the thread for the question

What's the highest average mph you've recorded?

!? strange, content doesn't fit the poll...

is nobody from germany posting here? the maximum speed option

True -- the poll and the title of the thread don't match

How is your Volvo on the autobahn?
