Green cotton filters

[CBass]

I am looking to replace the air filter on my LCR but I can't find the answer to my exact criterea query when searching.

I have narrowed the choice down to either a replacement green cotton panel filter (but I won't be smoothing the inside of the airbox) or a green cotton dynatwist induction kit.

Here are my questions:-
1) Currently unmapped, what are the pros and cons of each?
2) If mapped in the future, which would be best to have?
3) Do you have to move/cut/remove anything to fit the feed pipe through to the dynatwist(assuming you don't go for the biggest possible size pipe)?
4) Would a specialist garage do all the work for me if fitting the dynatwist, incl feed pipe?

I am hoping for responses specific to these questions but no doubt people will comment on other options, so what are they!?

Thanks.

1) Currently unmapped, what are the pros and cons of each?
Green filter can flow more than a paper filter and will do so longer than a paper filter would. more airflow, potentially a little more power.. focus on the "little" aspect

2) If mapped in the future, which would be best to have?
either Dynatwist OR panel.. but enlarge the feed pipe to the stock airbox and you can get equally high airflow from either. One is bling the other is not

3) Do you have to move/cut/remove anything to fit the feed pipe through to the dynatwist(assuming you don't go for the biggest possible size pipe)?
No, feed pipe on a dynatwist can go direct onto the rear of the headlamp where the original pipe went. No cutting

4) Would a specialist garage do all the work for me if fitting the dynatwist, incl feed pipe?
Any competant garage could do this. Panel filter is drop in. anyone could do this. dynatwist is disassemble some bits, bolt on a bracket (mod it a little when I do them for better fitment) and again job done.

Green filter is £36
Dynatwist is £170

you pays ya money and you takes ya choice.

Thanks for your email Bill.

I have decided to go with the dynatwist for my LCR225, if I phoned through and ordered it today, how long would it take to arrive? ie. would I have it in time to try and fit it over the Easter break?

Many thanks,

Chris.

 

[ibizacupra]

it will depend on if green importers have one..

 

[ibizacupra]

just ordered one in anyhows. hopefully with me tomoz

I have just phoned my insurance company to see what they say to this change and they want an extra 25% premium. Now I know you are not an expert in insurance, but I have suggest a max increase of 8bhp which is 4.5% (I assume it may be lower), would this be a correct figure in your opinion or would it be less.

The problem I have is that I said I wanted to add an induction kit and the kid said "What's that?" so I explained and he told me that the extra premium was becasue my car would have a 4.5% higher top speed which a) is very unlikely and b) doesn't mean I am suddenly going to start driving round at 155!

Can I get away with saying no power increase, or does it actually have a noticable effect? same with the panel filter, will I have to declare any power increase?

Thanks again.

I upgraded my air filter at the same time as my remap and a few other things, and each time I added a modification they asked for the power increase. I quoted a 15-20% increase for the remap and nothing for the rest.

I ended up paying about £85 more for remap, filter, dv and strut brace; but if I had just added the filter I think it was something like £45 alone. I'd tell them you are changing the air filter, but I wouldn't quote any power increase.

As for the 4% increase in power meaning you'll have a 4% increase in top speed.. well thats just not true otherwise a car with 450bhp would have a top speed of 300mph by that calculation In fact the general concensus is that to double speed you need 4x the power, but that's another story...

 

[CBass]

Thats what I figured, only way to find out is to put the car on a "reliable" dyno before and after and quote the change to the insurance company and that is a whole other can of worms...!!

mine was of course "replaced because the after marked cotton types last longer and provide more protection to the engine..." if they look it up thay cant accuse you of lying cause its true!!

Phoning the insurance co up to tell them you've put a different air filter on

Ok, each to their own, i guess it's good to be honest with them.

Here's a quick question, has anyone ever had the insurance company come out and look under the bonnet or test the engine to see if its been remapped? even after a crash?

I haven't!

 

[adam cupra 20vt]

No but having worked at a accident repair centre I can tell you that if they did find out they would void your insurance straight away....same goes for any mods not listed.

In theory yes, but thats normally things the insurance can see. Anyway i'm not going to get into a debate about it, you are right of course, but the insurance company can go themselves if they think they are going to rob me of more money because i've put go-faster stripes on my car.

 

[adam cupra 20vt]

I agree I would not tell them about a remap only things they could physically see.

 

[lordgibbness]

I did think about this but I have heard of cases where they won't pay out.

In my case I have a different diverter valve that they probably wouldn't even notice at the back of the engine bay, a cotton filter that they probably wouldn't open the filter box to look at and a remap they proably can't detect.

I just wanted to do things correctly and apparently the strut brace is a real issue if you don't inform them as a side-on prang can push the damage to the other side due to the rididity and increase the costs.

Then again I have things that I wouldn't even think of quoting: tyres, wipers, bulbs, etc. and the dogbone wasn't even on the system.

its an airfilter.. not a high performance power gain
insurance=scam

legalised robbery

 

[adam cupra 20vt]

I got a forge 007 valve, getting a re map and got a green panel filter on its way from Bill [cheers Bill]..............I've never seen a insurance assesor open up a air box to check a filter.....no way they can check for remap in a garage compound......and the valve is hidden under the engine cover so they can't see that either.

Its as good as standard

 

[D.K]

Going back to the air filter I would say the difference between an upgraded panel filter and a after market induction kit are going to be minimal, so for the increase in your insurance I'd stick to the panel which as other's have said is not visible, Also you will be saveing about £120......
Sorry Bill

 

[ibizacupra]

i have both panel filters in stock as well as a couple of large open cones, and dynatwist on its way

 

[CBass]

Here's the silly thing the insurance company said:
Induction kit = £71 increase
Replacement Panel Filter = £55 increase (that's each year to cover something which does nothing to increase power and only costs £30) !!!!!

I've been insured with the same company for 12 years, 5 with my LCR and 1 previously with a Pulsar GTi-R - never had an accident or claim, never had any points = perfect insurance risk but they still think I'll be a numpty as soon as I change the filter ... what on earth is going on!

It would help if you could actually talk to an underwriter rather than talking to a middle man who knows nothing about cars, talk about irritating!!

I wouldn't bother informing about a replacement panel filter but you would have to if you fitted an induction kit, couldn't really get away with that.

Sorry to mess you about Bill, I still haven't decided what to do...

 

[lordgibbness]

I think if I was just getting a panel filter I wouldn't bother, but seeing how my remap covered the cost of all my other items it was essentially free for me to declare the rest...
