I'll never understand the "stock is better than aftermarket" debate. It isn't your car, it's not your money spent on it, and it's not your time being used doing the work. If they want to do something different there is no need to throw opinions around. As for the "it protects against water" argument. If you're driving in that deep of water, you have other things to worry about. I like this forum a lot and don't want to see these stupid arguments. If you disagree, don't add anything that isn't helpful.

Lol, people ask for "opinions" then get cranky when they get them. Priceless!

True. I'm still wondering what the original does in terms of protection that you think is lost with these things, though. I've got a huge K&N on mine, and I'd be interested.

Most people know, I'm the poster child for maintenance. I also believe that 98% of what the car came with is better than mods that people do. Besides that, I agree with you, it's your car, do what you can afford. From my side of the fence, doing a mod that cost you $50 or $300 that doesn't really improve the car's efficiency, performance, or reliability is $50+ wasted.

If you do it for looks and sound or some other reason that gives you pride of ownership and encourages you to care for your car better, great.

As for the stock filter box arrangement, it is designed to allow you to drive through water about 6 inches above the top of the bumper for about 30 seconds, and at the top of the bumper level for a good while. The key is to keep water out of the cylinder so it doesn't hydrolock and bend a rod or cause misfire.

It really terrifies me to see those things hanging down closer to the ground.

Hmmm don`t drive through deep water. Don`t have that much water in Copenhagen.

My new cone filter is higher up than the original box and intake itseft is in same height as the original.

Now I get the air directly into the throttlehouse.
In the original way the air have to travel 50 cm into the box then turn around through filter and then 40 cm into trottlehouse.
How can my way be more bad ?

Not cranky about what he's done to his car, cranky at people that arguing over weather the stock air filter is better not. That wasn't the point of his post. It went off subject, and this forum is one of the few I've been on where people stay on topic and are extremely helpful. Except for this one subject for some reason.

Re PS78

1. Filter I got from here. Don`t know who produce it : http://www.carlab.dk/shop/sportsluftfil ... 5287p.html

2. On my 1992 maf house is built into the airfilter lock, but from 1997 the maf is in a seperet house : http://www.ebay.com/itm/Mass-Air-Flow-M ... odel%3A850

3. Short hose is like this : http://www.thansen.dk/bil/autoreservede ... 469928642/

4. This is the original hose from trottlehouse to airfilterbox : https://www.aliexpress.com/item/Engine- ... .18.NYOZfK
(You use the bottom part of it with the two connectors)


So filter to maf house with clamp and maf house to short hose with clamp and short hose to lower part of original hose with connectors with clamp :
1 to 2 to 3 to 4 hope that will give you the picture

Havn`t tested it yet, but at the same time I ajusted the cams (exhurst cam 3 gr avanced) That I could fell.

PS the sound you hear in video is not only from the airfilter. Got a 2,5" simons exhurst on.

Thanks for the details. Looks like a good, clean set up. Since I've dealt with my car's Christmas list of issues, it's time for a little bit of fun.

I see what Robert's saying - as with 99,99% of things that Volvo does, the stock setup is very well thought out and reasoned through, so for someone who's the "poster child for maintenance", experiments like this might be not be their thing.

That said, Volvo tends to err on the side of extreme caution. The V70s and 850s were marketed as luxury cars, but they still thought that they should allow for someone to be stupid enough to drive their car into water reaching 6 inches above the front bumper. Also, they set up their T5 engines to produce 226 HP, on an engine where a tuning will yield 300 HP and on stock internals that easily handle 400 and an automatic tranny that can handle 300 (not to mention the manuals...).

Most things that we do, like replacing the stock filter and box for an open cone filter, will probably override some of Volvos intended "margins", but only extreme modifications will actually make something fail. All my own, unskilled opinion, of course.

I like the cone filter - even on an NA, but I see Robert's point. So OP better not be driving through water above waist height.

You must know that Volvo do all things the most safe way (too safe ?)

There are allways room to better things and make them more effective.
Volvo make things to fit all kinds of people in the most safe way.

Take the plastic on disc in trottlehouse. It`s there to make a smooth and safe ride.
Take it of and you get better speeder respone, but Volvo does this to make it safe.

Volvo is all about being safe. They live on that.

PS I work at Volvo

Lots of space in engine compartment now.

PS if you want to do like me with open filter and have maf in filterhouse and want to use seperat maf house,
then use your old maf sensor. Car will not work with sensor from newer model.

[abscate]

Only down side I see is loss of temperature control to the input air in cold climates. Not so important with a turbo but for an NA that would suck.

Jantt...congrats on your first Gold swimming medal since 1948! It was a bad Olympics to try to win medals against the US but Blume came through!
