Cone filters

[Garfy]

Good morning folk, looking for a cone filter for my 2, is there really any difference  between a K&N filter and a 15 squid e-pray one?

[shnazzle]

Yes.
Definitely.

If you can find cotton replaceable (not washable) ones, they're your best bet for filtration. Assuming you're just after the noise anyway right?

If you need the extra throttle response/flow, go for a good quality Green filter. K&n in the end is a bit on the poop side.

Miss the noise from my MGF with one, serious smiles  :-) :-) :-)  if I can get extra flow in as well, all to the good. I expect that comes at a premium, time to search for what's available.
Any pointers in what I'm looking for?
In the future I will be looking towards the MAF MOD if that has any bearing on the decision  :-) :-) :-)

Not really  s:) s:)  Plenty air coming in.
Stock engine can only physically pull in about 185cfm air. Stock cotton panels are rated to 300+,at least.
Good cones 500+
Bad cones sometimes less than 300 but the important thing is the filtration vs flow. That's my main concern with cheap filters.

K&N only get my down-vote because if you get the oiling wrong, you drastically reduce the flow performance of the filter.
I measured lower flow on the k&n than on stock panel. But, that was after I oiled it. I suspect I over-oiled. But there's no way to know what is too much or too little.

Thank you sir  :-) :-) :-)

Also worth noting that you would need to mount the cone filter behind the battery to avoid too much heat soak from the exhaust.

Good point. I assume that's where everyone puts it haha.

The only other solution I think I saw once that I liked was the stock airbox removed and replaced by a carbon fibre canister with a direct feed from the stock pipe that runs along the nearside rear wing.

So basically just replacing the stock airbox for a cone with heat-protective casing. Nice way to get a bit more roar while keeping all the stock pipes and easily accessible filter.

We could do with a decent supplier of the Apexi filter. They were always excellent in the past.

Lets be honest - we all know cone filters don't improve performance and they let in more fine particles. The only reason for fitting a cone filter is induction noise

That's what I keep saying!

But the noise is rather glorious...

Can you recall the carbon canister solution you saw please? Only I'm after a setup that gives me the 'sound effect' without sacrificing too much performance by way of flow.

Sorry I cannot. Might have been a custom jobbie. Easiest way to add roar is to remove the pipe behind the nearside rear light. It essentially turns it into a cone filter

I have a BMC CDA that is, IMO, the nuts. if a tad expensive.

it used to be routed to the original position but since moved behind the battery and you can just about get it in.

if i can work out how to put pics up ill find some.

I had the same as Dan but not got the car no more so can't upload a pic I'm afraid
