Full flow 'sports' air filters

[Alec Dawe]

Can anyone tell me who supplies these nice shiny, full flow, drum type sports air filters to fit a 240, and roughly what they should cost.
Had a look in Hellfords today, and they are talking about £120ish?

There must be someone better than that.

Anyone out there using one on a 240, and noticed any difference in the car?

Hi,

You maen something like this: Linky...

Although they do not list the 240 they may be able to supply. See here: Linky...

Ahh yes. Worse filtration gives more engine wear. Stock filter is not restrictive anyway. Sucking in hot air from the engine bay will give you worse performance.

Of course they sound good...

Hello Alec, if you can get a hold of another black pipe, from air box to engine, then remove the air box and cold start hose, put the 2 pipes together and tape up with black tape (gaffer) and place the free end infront of the radiator with a cone filter from your local motor factors, this will give the maximum cold air access ffor the engine, I've done this with a small improvement in throttle resonse and a minor improvement in mpg, possibly an extra 2mpg per tank.

Hi go here think they do the full shiney filter

I run cone filters and shiney filters (depends which is being cleaned at the time) and my engine has not suffered any more wear. I have to disagree with you on the statement of the stock filter being restrictive they are very restrictive although cone filters and shiney carbon ones may not give the 3-10bhp increase they certainly do increase throttle response.

They may increase the perceived throttle response because of the noise stimulas but real reponse would be undetectable untill at least 5000 rpm and who the hell goes there. Regards Peter

Well I've been known to venture a little past 5K rpm, but it has been proven that the standard air intake is restrictive and can be improved upon to great effect, a cone filter with a good cold air source is dyno proven to be an improvement on the standard system, yet again this is one of those things that is up for debate, but I do find mine quicker than standard.

The old saying of intake, exhaust, suspension from a tuning guru Dave Walker springs to mind.

Anyway best of luck with it.

Best way to find out if they are allowing more crap in to your system is to change the oil @ the same time..... Leave it 3K miles have it analysed & if your sillicone levels are elevated .......... Summink is letting crap in ..........

Cone filters... real ones..decent ones.. should be as restrictive (as in ..'as good a filtration'..) as panel filters inch squared of surface area for inch squared of surface area.As Andrew says, stock filters arent restrictive. Cone filters come into their own flowing more air through the total surface area available... A cone filter provides more filter surface area than a standard panel filter.
Most of the filters available from Hellfords (cheap ones) as Andrew says will give worse filtration (use of inferior,cheap filter gauze, etc) and possibly more engine wear.
Sucking in hot air from the engine bay will give you worse performance, again as Andrew says, however I would imagine most on this board appreciate that anyway and would take steps to improve the air flow to the filter in the first place!

It is however a pointless waste of time (IMHO) Improving the breathing of an engine without allowing it to exhale the waste product better. If an Engine is bunged up with backpressure (read standard) then allowing it to be able to draw more air in will have negligable effect.


Welcome to Conefilter Anonymous. I am Tim and I run a cone filter and Race backbox.

My method of improving a car is suspension, exhaust then intake.

A good cone filter such as JR K&N will improve throttle respons on a 200,300 and 700's Yes the original item is a very good flowing oem fit filter.
The cone filter fitted by the engine is likely to reduce performance to to the air being warmer (on LPG this does not make as much difference). Situated in a nice cold air feed the filter will improve power in the full rev range (volvo std engine idle to about 7500rpm)
We do basic cone filters that can be fitted directly the the AFM ot the throttle body and two types of direct cold air feed systems. 1 kit is a filter with two lengths of pipe that you can cut to suit your needs and the other is a carbon fiber incased filter with direct cold air ducts.
The advantage a sports filter gives you should never need replace it only clean them.
