I took the air filter out for a clean yesterday, and found it was really, REALLY oily. Now, I know you impregnate filters with oil for driving in desert conditions, but in England??? 
I'm guessing it's not supposed to be this bad.
I'm currently hovering over the TVR-Gear "buy" button on a replacement one at £23... before I click the mouse-button, has anybody noticed any real improvement from cones/other configurations, etc?
[Edited to add]: Or do you guys generally just soak the existing one in petrol for a while & dry it out?

Should be oily to collect dust and muck from the air. If you don;t oil it you may as well leave it out as it won;t stop half the damaging particles that it should. Foam Elements don't catch anything like the small particles that woven paper ones do anyway.
I'm talking the kind & amount of oil that took a good few minutes to scrub off my hands; it just seemed almost waterlogged with it.
I've just replaced my original filter with 2 BMC 'twin-cone' filters, fitted onto the end of the airboxes.
Part number TW90-130, its a Porsche fittment which allows for the air temp probe to be moved to it. (the other side requires blanking off).
Cost - £100 all in, ordered over the counter from Halfords.

I too had what seemed excess oil, which has dripped down through the air intake on the front panel not long after a service....phoned the dealers to be told this perfectly normal as they 'spray' the cloth filter with an oil to prevent particles of air passing through the 'dry' filter....needless to say i havent seen any more oil on the front panel since!

I'm currently chopping and changing between the original foam and some cone filters.
The cones make the engine sound a bit more raw, however I had problems with misfiring if driving in heavy rain. Not having the foam in the front compartment just forces rainwater into the engine bay. This was only in really heavy rain though.
Not sure if I'll keep the cones, but i'll try them again when the weather gets a bit better.
I can see how that could happen.
I'll probably remove the 'scoop' part of the front air cleaner, as without the restriction of the original foam element a lot of air will be flowing through the engine bay.
But before I do that, I'll need to put some sort of mesh in place as otherwise the radiator will be too exposed.

Yeah just stick the boxes in place of the flexible pipes and then attach the airbox and remaining pipes to the cone cans. Nice cold air feed.
What filters do the cones use as woven paper is more restrictive than the foam...
I've read that a few times, but can't work out what you are suggesting. The cones are much larger than the pipes.
Well that won't work then. You'll need to get some larger pipework.
You need to try and keep the cold air feed from the front as putting 2 cones on the end of the air boxes will just suck in hot air and potentially cause you more detonation problems etc etc.
Even just supporting the feed pipes from the air box in front of the cones would be better than nothing.
