Found this - makes sense doing it then?

Horsepower You Can Feel
As with all K&N kits, when you bolt-on a 57i intake, you will notice the difference the next time you drive your Volvo V70. K&N 57i Gen I Intake Kits are a great way and in many cases the only way to maximize airflow and engine performance. They will replace the factory air box providing both High-Flow air filter technology and a larger air filter size. This winning combination will increase horsepower and sound great too.
Break Out of The Factory Air Box57i Series Intake Kits are specifically designed for each different vehicle and will free your V70 from the size restriction that comes with the factory air box. These economical kits can take a variety of different forms based on vehicle characteristics and available space under the hood. Each kit is designed to provide power throughout the RPM range. Gen I’s take advantage of the added airflow provided by an oversized air filter released from the restrictive factory air box..
These kits bring engine airflow out of the factory box by providing a large size open-air conical or round High-Flow Air Filter. The extra surface area of these open-air air filters provide even more airflow at lower restriction than a K&N O/E replacement filter which is always limited to the size of the factory air box. The larger air filter also captures and holds more dirt increasing its service life before a cleaning is required (up to 100,000 miles). The filter is then either directly attached to the engine carburetor or throttle body or indirectly through a tube assembly running from the filter to the engine. All adaptors are made from high quality materials such as steel, aluminum, silicon or reinforced nylon and ensure long life.

I was going not to do it in case of problems with the maf sensor.
The 2.5 se non turbo has already 167k on it, so first I thought I'll do it as it sounded great on my last car.
Then, I seen loads post with tunned cars where the maf sensor packet up.
So, I stopt of thinking about, but still had it in my mind all the way along.

Which of you did it and is it giving any problems with the maf sensor or other engine related issus?

It is a 2.5 20 valve autobox phase 1. Non turbo, pre me.

Anything I need to know about where or how to proper install it, or what cone Airfilter I need to use, should use, and maybe any other Important informations I would need for doing this modification.

I'll seem loads of them Airfilter cone systems for sale, shops ebay, etc, would it matter what system to use as well, or what size cone I need. On my last car, 6cylinder Honda engine I had a standard cheap one with a massive cone on.
The only thing I had to do was making the room to suck cold air in, as it was original located behind the lightcluster and would not get airflow from driving without a special made airflow from the front of the car.

Is this the same on the v70 as the box is located behind the light as well?
Using a scoop or build a airflow suction system from the front (next to the foglight or so ) to ensure air intake guarantee to the cone filter?
Seen a modification where someone cut the wheelarche out to give the cone Filt fresh air intake, but the prop,em was on puddles as it would splash water on it.

So with the uk specs water problems I rather would use a scoop on top of the bonnet to
Thanks guys.

Sorry, that was much to hard to read, but best advice is sell your car and buy a T5.

[p fandango]

the only reason the MAF's pack up after fitting a cone filter is because of excess oil on them, even a new filter it wouldn't hurt to give it a good rinse under the tap & let it dry naturally (& DON'T RE-OIL IT)

personally i had a K&N 57i on my 854 T-5, & noticed a bigger improvement when i swopped that to a Pipercross cone filter

[v70tom]

I had a standart cheap cone filter on the Honda v6 engine.
It was a big thing but nothing special.
It improved the engine performance.
But I never had problems with oil or even put oil on.
Why oil ?
That's new to me. I run this one like it came out the package. Just remove the original air box,
Put extensions on and filter. That's all it was.
Is there something else out ?

And, yes I would like a t5 but is older and I like the painted bumpers, doorhandles and front on he v70phase 1.
I have a t5 down the road and the front looks compare to kind a bit outdated and plumb.
Sorry, no offence.
With the painted parts and the more modern front bumper a t5 would look great in my opinion.

But I stick to my v70 as I spend quiet a bit in it and don't like to loose out on it, althought start
Again with spending on another car and have all the work until, it's done as I want it.

I ment a V70 T5

Most of the cone filters or free flowing filter elements use a cotton gauze. The cotton itself doesn't do the filtering but is there as an agent to hold oil that you spray onto it which is what traps and holds the dirt. Like Pedro says usually MAF problems happen because the filter is over-oiled and the oil gets onto the the MAF which it doesn't like !

[v70tom]

It would be a standart cone filter without any oil in or on it.
Just paper cone.
Tis should be ok then?
Did not know you can have them with oil. Lol

[v70tom]

Would like one but too expensive for what you get.
And, did all the work on mine so I wouldn't get the money back if I selling it.
Misses don't want home as it is too big for her. Lol

[v70tom]

The plan was to remove the box right where it is attached. So leave the maf and the stubby attachment for the box.
From there get the cone filter straight on.
To get enough outside air, using the original channel for the airbox to feed air from the front of the car, and additional over a scoop form top of the bonnet with a channel build under the bonnet to bring the air from the hole inside the engine bay back to the front on top of the Airfilter cone.
This should avoid the Airfilter suck the hot air produced by the engine inside the bay.
At least in theory.

That's right ? or do I miss something?

I know is not a turbo but if it helps and makes the performance of the 170bhp engine better ill go for it.
Not many people would know what's under the bonnet, so I am not so bothered.
Aim quiet happy with the 170 bhp for the roads I using anyway.

F&r speed I always have the gsxf.lol

[M-R-P]

Pulling warm air from the engine bay makes no difference to normal driving, even with a turbo. It's only if you're racing the car and spend a while parked with the engine running, waiting to go on track you'll get "heat soak" which will clear pretty quickly once you're moving.

Furthermore, it's been proven, albeit with some degree of controversy, that performance filters and induction kits offer little or no performance increase at all and in some cases, actually hold the engine back slightly.

The best thing you get from a free flowing filter is the noise. On 5-pot cars it's a very nice noise too Take the insulation mat from the inside of your bonnet for even more noise

[v70tom]

Ok. Thanks. No need for hole in bonnet for cold air flow.
Just the cone on and that's it.

[M-R-P]

It's all I've got...

[jotter22]

You have a cold air feed to the standard air box any way so just utilise that as your cone will sit in the same place as the removed airbox!

Tony.

[v70tom]

That's cool. Ok. I'll do that then.thanks

[v70tom]

Ok, just quick - if I remove the air box ( red marked ) after the sensor before the box,
Where it is mounted together, that's where the cone can go without problem I assume.

What about the pipe ( marked with blue arrow ) a this pipe is connected to the air box at the bottom.
Do I need to reconnect this somewhere else, what function is it for, or can I just leave it hanging lose without any affect on heating, air an or engine ?

Thanks

[jotter22]

Sorry Tom mines ME7 and piped different to yours someone will advise you soon mate.

Tony.

[Tomcat]

Best thing to do is to just take the top off the airbox, put your cone on the end of the pipe (the big one with the sensor) and sit it in the bottom half of your airbox, that way you've still got a cold feed to it and the rest of the plumbing can stay as it is.

^^^what he said^^^

[M-R-P]

The pipe marked in blue is a hot air feed from the exhause manifold area. Not sure why modern cars still do this as you may as well throw it in the bin lol.
Rip the maf housing out of the airbox lid, ram the filter on the end and rest it in the lower half of the airbox et viola! job's a goodun

Rip it out?
Erh? Could you please explain what you exactly mean by hat? Lol
Is there no need for on the pre me engine or is not a good idea leave it on while using a cone filter?

I would just leave it where it is as it sits on the pipe where the box attached to.
Leave the bottom of the air box sounds ok, but I need to cut the box out to fit the filter, otherwise
I have to get he scoop on as the filter would sit on top of the box and the bonnet has a conflict with it by closing it.
( at least so far I could tell while I tryd it last night without actually doing it about darkness.
Just put it on and it don't go inside the box.
May just cut the ox. Is only 1 or 2 cm I guess.)

I'll try tomorrow with more time and daylight. Thanks guys.

Looks like I looking soon for a t5 lol.
