Technical Which cone filter?

[daz666]

Would a cone filter increase the performance of my 20vnt? It is a standard coupe but has a square, flat metal air filter. The car is a little sluggish compared to my 16vnt. I have changed the plugs to bosch super 4's and have put new coil packs on. I have also used a fuel tretment to clean the lines etc but it still feels a little sluggish. Everything else runs fine but I feel it should be a little quicker than my 16v (wich has no mods at all)...If I get rid of the plastic filter box and piprwork and placed a cone filter on would it be more responsive? If so, which one would be best suited to this model?

Thanks

an £8 ebay twin cone will do

Don't expect much just by adding a filter. Obviously this will help the 2 litre lump to breath bit better. Ideally you want to add a s/s zorst & I think there is now a chip for this model.

You may well find it feels more sluggish with a cone. you'll lose some low-down torque and replace it at the top-end. I'd stick a K+N panel in your airbox for now, £20-£40. If it's feeling sluggish, Perhaps consider a G-Tec 1 chip, you'll need a boost gauge for this though. Or how about a re-map? I've got 50 extra horses for £175 this way.

I think its a non turbo 20v pinin_prestatyn.

Still I need to get my air filter tomorow and i was wondering if a cone filter is best type?

 

[ChrisUK]

No it isn't. As said high flow panel filter is better. The factory airbox setup is better than most companies aftermarket attempts.

 

[pinin__prestatyn]

Cone can sound ace though. Apexi are good. Dry type too. I've got a Blitz stainless mesh type and it sounds the mutts nuts.

As above cone sounds amazing on a N/A you can hear the 5pot warble. On the turbo you get a huge whoosh and sucking noise as though small children and grannies will be sucked from the pavement and into the engine

is this the 147bhp or the VIS 155bhp version? dont bother getting a cone for the VIS, but if its the 147bhp then ITG, BMC, Apexi, AEM are all good filters. Or even keep your panel filter and try a BMC panel or K&N

I came in possession of a double mushroom filter, the foam was blue Cost me nothing, so....ach I would bang it on the Coop. The sound was amazing but it kept throwing up a maf fault on my widget. It seems the Coop didnt like the turbulent air flow caused by this system. Even at my age the noise was brilliant but I got rid & have used a free flowing panel ever since......

strange... the cone filter I put on my 147bhp coupe did not give any issues and the new owner who I know still has it on has had no issues in the 3years. Although mine was a single cone, maybe the twin cone was allowing too much airflow

 

[jimboy]

Yes you're quite right in saying a cone usually doesn't give any issues. I know many Coop owners who are quite happy with a cone, but in my case well I just didnt like taking any chances. As all we Coop owners know the Coop can be temperamental at times.

Very true, in the space of just a week I can feel the following towards the coupe,

:bang: :idea: :idea:

 

[ChrisUK]

:yeahthat: too true.

Mine needs a few things doing and keep putting it off due to other things taking priority and its doing my head in . Thinking about selling punto and putting ALL the money into the coupe .

 

[jimboy]

Indeed, for the money nothing comes close to these. Personally for what they are I dont find them that expensive. You cant really skimp on them & they are a bugger to work on, but even at my age every time I get behind the wheel of my Sprinty, I catch sight of myself in the mirror with a daft grin on my face I've had/driven many cars in my time, probably three figures (not all mine) This has to be the only one I can honestly say I get a bit that way in the stomach,( in a nice way) every time I drive it.

I've said so many times before, there are times I think of the money wasted on my of love cars, this is not one of those moments

At normal power,I would say that a cone filter adds some noise and that's about it.
When you are going for around 300 or more,I would have thought a cone filter would allow more air into the system and so enable more combustion ?
That's my way of thinking and I have read that a cone filter on a standard engine may decrease performance low down the rev range......again I am not 100% on this.

Correct. I fitted a cone on mine and lost low end torque although the turbo seemed to spool a little quicker (although placebo effect probably). I went back to my drilled air box and high flow K&N panel filter .

 

[Sniper]

I have decided to get a induction kit when im running more power, for now im think im gona just get the high flow k n n panel filter like chrisuk.

Do you get the turbo sucking nosie as you do with the induction kits?

 

[ChrisUK]

Yes you hear the turbo more than you would. But then again the previous owner drilled the bottom part of my airbox to allow more air in and noise out lol.

ill be using my cone but im hoping for about 280-300 bhp from mods:
